Hup San Social Club: Singapore’s Pocket-Sized Nightlife Hideaway

If you’ve walked down Club Street in Singapore without knowing what to look for, you probably walked right past it. Hup San Social Club sits hidden in the basement of Club Street Laundry—essentially a speakeasy with no street-level sign, just a humming red light above the door. The bar seats exactly 12 people and opened in April 2025.

Location: Club Street Laundry basement, 98 Club Street, Singapore · Owner: June Baek · Hours: Tue–Sat 6pm–Midnight · Reservations: None (first come, first served)

Six key details define this pocket-sized speakeasy.

What is Hup San Social Club?

Hup San Social Club is a 12-seater underground cocktail bar tucked beneath Club Street Laundry at 98 Club Street, Chinatown. The venue describes itself as a love letter to Singapore’s early Chinese immigrants and their social club culture. The name Hup San ( ) translates to “Harmony Life,” a direct nod to the communal spirit of those early societies. The building itself previously housed Hup San Laundry in the early 1990s, giving the space a literal connection to its past.

Location and access

There is no street-level signage. The entrance sits at Club Street Laundry, and visitors should look for the humming red light above the door. Once inside, inform the staff that you’re heading to Hup San Social Club. The venue occupies the basement level, creating that hidden speakeasy atmosphere that has become increasingly rare in Singapore’s nightlife scene.

Inspiration and concept

The concept draws directly from Singapore’s historic Chinese societies—places where early immigrants gathered to socialize, conduct business, and maintain cultural connections. June Baek, the Korean-American owner and beverage director, has layered her own heritage into the concept, blending Korean elements with Singaporean flavors and a generous dose of nostalgia. The debut menu title, “Do What Brings You Joy,” reflects her philosophy.

Size and vibe

With only 12 seats, the bar achieves an intimacy that larger venues cannot replicate. Reviews consistently describe it as a dark underground den that fills quickly, with an atmosphere suited to intimate conversations and date nights rather than large gatherings. The tight space means you’ll likely rub elbows with strangers, which, given the communal spirit the bar honors, feels entirely intentional.

How to reserve at Hup San Social Club?

The short answer: you don’t. The bar operates on a strict first-come, first-served basis with no reservations accepted. This policy stems from the venue’s small size and consistently high demand. The official Club Street Laundry site states it plainly: “We fill up fast, and we don’t do reservations.”

Reservation process

There is no online booking system, no phone number to call, and no waitlist to join. The only strategy is arriving early. Given the 12-seat capacity, the window for securing a spot is narrow, especially on weekends.

Best times to book

Arrival before 7pm on weekdays offers the best chance of finding a seat without a long wait. Friday and Saturday evenings will almost certainly involve queuing or being turned away entirely. The bar opens at 6pm Tuesday through Saturday, so timing your arrival for opening or shortly after provides the highest probability of entry.

What is the Hup San Social Club menu?

The cocktail menu, titled “Do What Brings You Joy,” features 14 signature creations alongside 18 classic cocktails. Prices range from $20 for a gin and tonic up to $27 for more elaborate constructions. The menu draws heavily from June Baek’s Korean heritage while incorporating Singaporean ingredients and flavors that evoke nostalgia. Spirits featured include baijiu, soju, and plans for Japanese shochu additions.

Signature cocktails

The debut menu’s standout drinks showcase the bar’s playful approach to mixology:

• Cold Soup ($26) — Soju with kelp dashi, sesame, cucumber, and apple vinegar. A cold soup served as a drink, earning its name literally.
• Achar ($25) — Named after the pickled vegetable condiment common in Southeast Asian cuisine.
• The French Fries 2.0 ($26) — Whisky infused with fries, finished with Heinz ketchup. A bar snack elevated to cocktail form.
• Camellia ($25) — Rum with galangal and rose, offering floral and spicy notes.
• Mala Diwa ($25) — Sichuan pepper, watermelon, and strawberry—a fusion of numbing and sweet.
• Pumpkin Ma Heart — A seasonal or rotating option showcasing ingredient-driven creativity.

Classics menu

For those seeking familiar territory, the classics selection includes:

• Gin & Tonic ($20)
• Negroni ($27)
• Old Fashioned ($27)

The bar also maintains a connection to the upstairs sister venue, Club Street Laundry. Patrons can order mains from the modern Australian menu ($23 and above) to be delivered downstairs, and vice versa. A small bites menu is planned for launch in the quarter following the opening.

What is the dress code at Hup San Social Club?

No explicit dress code is mentioned across any published sources. The venue’s casual speakeasy vibe suggests smart casual as the safe choice, but the absence of an official policy means you’re unlikely to be turned away for being underdressed. The bar attracts a mixed crowd interested in good cocktails rather than appearances.

Expected attire

Based on comparable venues like Atlas Bar and similar speakeasies in Singapore, the typical patron dresses smart casual—clean, presentable, and appropriate for an intimate bar setting. Jeans and a button-down shirt will likely fit in without issue. You won’t find anyone in shorts and flip-flops, but overly formal attire would feel out of place in the basement den’s relaxed atmosphere.

What do reviews say about Hup San Social Club?

Early reception has been markedly positive. Time Out Singapore called it “a pocket-sized, dark, underground den that’s perpetually packed,” positioning it as one of 2025’s most exciting openings. Honeycombers described the menu as revolving “around curiosity and nostalgia, and they nailed it.” HungryGoWhere’s assessment led with “vibey bar tucked away right below Club Street Laundry,” emphasizing the hidden gem quality.

Popular feedback

The consensus centers on several recurring themes: the intimate atmosphere created by the 12-seat capacity, the playful and well-executed cocktail program, and the speakeasy thrill of accessing a space with no visible signage. The bar’s connection to Club Street’s history also resonates with reviewers who appreciate venues with genuine roots rather than purely commercial motivations.

Crowd and atmosphere

The venue attracts small groups and couples rather than large parties. The tight space naturally limits group size, and the no-reservations policy means most visitors are either regulars who know the drill or curious newcomers who stumbled upon it. The atmosphere skews toward conversation rather than loud music, making it a genuine date night destination rather than a pre-game spot.
