The Cold Soup at Hup San

A small white ceramic bowl arrived on the counter with a glass straw resting on the rim.

The liquid inside was pale green, the colour of a cold pea consommé thinned with cucumber juice, with a film of chive-and-olive oil floating across the surface and a few toasted seeds at the edge. The instinct was to ask for a spoon. The bartender pointed at the straw. Despite the dish-form, the drink is a cocktail.

That bowl holds the room's working position in one piece of serviceware. Hup San Social Club is not really a savoury-cocktail bar in the way the press has been writing about it. It is a basement bar that has stopped pretending it is a separate operation from the kitchen above it. The pea water that builds the body of the Cold Soup comes from Club Street Laundry's mise en place. The chive oil on the surface is the upstairs kitchen's chive oil. The Achar cocktail later in the night carries a clear reference to the kitchen's house pickle. The bar drinks what the kitchen prepares. The drinks themselves are downstream of what the kitchen has been doing in the morning.

That integration is the bar's actual editorial centre. The savoury register, the hidden basement, the twelve-seat format are the room's structural condition rather than its argument.

Hup San opened in early 2025 in the basement of Club Street Laundry, the modern-Australian bistro that anchors the corner of Club Street and Ann Siang Hill at 98 Club Street. The bistro upstairs is what it is. The basement is the bar. Twelve seats, no signage, the kind of small downstairs room the city has been opening at the rate of one every six weeks for the last three years. The bartender is June Baek, with a long career through Mandarin Oriental's MO Bar and the Madame Fan kitchens, both of which sit at the marquee hotel end of the city's bar register where a bartender's personal palate is filtered through an institutional house style before it reaches the drinker's glass. Hup San is her first solo-led room. The debut menu, Do What Brings You Joy, runs fourteen cocktails and skews almost entirely toward a produce-forward register her previous rooms did not, by their own calibration, fully allow.

The Cold Soup is the menu's clearest statement of what that register is, and of how the bar got there.

A cocktail that is also a service relationship

The first sip was the test, but the test was structural before it was sensory. The gin base was the spine, a softer, more vegetal style with the juniper pulled toward the background. The pea-and-cucumber were doing the structural body work, producing the clean cold-broth register the bowl had promised. A small amount of fino sherry gave the drink a saline edge that pure produce could not have provided. The chive oil floating on top was the textural and olfactory surprise, fatty, savoury, herbal, the kind of weight that most cold cocktails specifically design out of the build. By the second sip the drink had stopped reading as a novelty and started reading as a properly built cocktail whose ingredients happened to have come from a kitchen rather than from a bar's standard stock.

That last clause is how the bar works.

A cocktail bar can produce a savoury drink without being operationally integrated with a kitchen. It can buy the pea juice, buy the chive oil, buy the cucumber, infuse them through its own clarification programme, and arrive at a competent savoury cocktail. Most of the city's savoury-cocktail rooms do exactly that. What Hup San is doing is harder and quieter: the bar's ingredients are not bought, they are downstream. The kitchen upstairs cooks the peas and reserves the water. The kitchen's house chive oil is the bar's chive oil. The bar's Achar pickled-pineapple-and-cucumber base is the kitchen's pickle base, with the bar's small additions on top. The bar is not buying these from suppliers. It is taking them from the kitchen.

That operational arrangement is rare in this city. Most cocktail rooms run as separate operations from any restaurant they happen to share a building with. The bar has its own buying programme, its own stockroom, its own preparation routine, and the kitchen has its own. The two operations meet at the wallet, not at the mise en place. Hup San has refused that separation. The bar is sized, twelve seats and two staff, for the volume the upstairs kitchen can comfortably supply ingredients to. The menu is built around what the kitchen is already doing. The cocktails are downstream rather than parallel.

The Cold Soup is the cocktail where that arrangement comes into view.

Where the bar slips toward the easier register

The drink where the bar's working method lapses into the more performative gesture is the French Fries 2.0.

The cocktail itself is well constructed. A roasted-potato-water infusion does the structural starch body. A brown-butter-washed vodka does the fat work that the dish form references. A small amount of tomato leaf provides the savoury herbal lift. A vinegar-tomato gel on the rim provides the "ketchup" reference without committing the drink to the sweetness commercial ketchup would have brought. The build is real, and the components are sourced through the same kitchen relationship the Cold Soup runs on.

What pushes the drink off the bar's working register is the presentation. The cocktail arrives in a paper cone with a few golden batonnets sitting on top and a small dish of what looks like ketchup next to it. The actual cocktail is in a vessel underneath the cone, and the drinker has to lift the cone aside to reach the liquid. The first sip is spent absorbing the visual gesture rather than tasting the drink.

That theatre is the bar's most overreaching move. The rest of the menu has been carefully refusing the gimmick. The Cold Soup is presented matter-of-factly, the Achar arrives in a standard cocktail glass with a small dust on the rim, the Martini comes as a Martini. The French Fries 2.0 wants the drinker to register the bar's cleverness in a way the rest of the room consciously does not. The drink would have been more honest in a standard glass, with the kitchen's potato water and butter doing the structural work without the cone.

A guest who can absorb one slightly performative gesture will not find Hup San a difficult bar. A guest who is allergic to performance on the bar should order the Cold Soup or the Achar and skip the Fries.

The room and what it does and does not do

The twelve-seat format is the right size for the kitchen relationship. A larger room would require more ingredient volume than the upstairs kitchen could comfortably reserve from its daily prep. A smaller room would not be operationally viable as its own business. Twelve seats is the operational sweet spot, enough demand to make the bar work, not so much demand that the kitchen has to start running parallel preparation for the bar's needs. The pricing reflects the operating economics: $25 to $26 per cocktail is at the upper end of what serious Singapore bars charge but below the marquee hotel rooms Baek came from. The bar does not feel cheap. It also does not feel like a hotel.

The service is calibrated for the small room. Baek and one other team member work the counter together, with the kind of efficient two-person rhythm that twelve seats and a slow-build menu require. The bar's most useful operational choice is that the team explains the unusual builds without performing the explanation. The Cold Soup arrives with a brief "drink the cup before you stir." The French Fries 2.0 arrives with no narration at all, the cone being the explanation. The Achar arrives with a quick reference to the upstairs house pickle. None of these explanations stretches past one sentence. The bar trusts that the cocktail is the cocktail and that the drinker can read what is in front of them.

The pacing held across the room's slow fill. By eleven the basement was full, and the bar was still moving at the same pace it had moved at nine. The two-person team can carry the format. It does not work at a larger bar.

The friction

The friction with Hup San is the friction the format inherently produces.

A drinker arriving for the more familiar sweet-cocktail register will find the menu narrow. The bar makes a small handful of concessions toward more recognisable builds, but the editorial centre is firmly in the savoury register, and the menu does not really accommodate the drinker who wants the standard cocktail-bar tier. A guest who walked in without knowing what the bar's working position is should sit at the bar and ask, rather than ordering blind off the menu card.

The other friction is the price. Twenty-six dollars per cocktail is at the upper end of the city's serious bars, and the format does not give the drinker the option of a casual lower-cost order. The bar is what it is.

The third is the dependency. The bar's working method depends on the kitchen upstairs continuing to produce the ingredients the cocktails are built on. If Club Street Laundry's menu shifts substantially, the bar's ingredient supply shifts with it. That dependency is the operational risk of the integration that makes the bar interesting in the first place.

What the bar is for

Hup San is one of the rare new Singapore cocktail bars where a bartender's actual working register has become the bar's editorial centre, and where the operational integration with a kitchen has become the working method rather than a marketing line. The Cold Soup is the drink where the integration is visible. The Achar is the drink where the kitchen's reference is most direct. The French Fries 2.0 is the drink where the bar lapses into the easier theatre the rest of the menu refuses.

The Cold Soup, in its small ceramic bowl with the chive-oil film and the fino sherry edge underneath the gin, did the kitchen-and-bar integration in one drink. A bar that has decided to be downstream of an upstairs kitchen, rather than running as a parallel operation that happens to share an address, is unusual in this city. June Baek has, drink by drink, made the arrangement the bar's editorial centre rather than its operational footnote.

The drink is what makes the case, and the basement is just where it happens.
