Top 5 Best Dim Sum Buffets in Bangkok (No Reservation Needed)

A longtime local favorite, Yok keeps Bangkok’s dim sum scene honest with a broad, value-driven all-you-can-eat spread and a dining room built for throughput. Walk-ins are the norm here, and even at peak hours the queue tends to move quickly thanks to ample seating and efficient service. Expect Cantonese staples like plump har gow, pork and shrimp siu mai, silky cheong fun, char siu bao, deep-fried taro puffs, and custard lava buns, plus congee, noodles, and classic Chinese desserts. The vibe is lively and family-friendly, with carts and trays circulating at pace. Time limits and last-order windows apply, so arrive early or late in the lunch window to minimize your wait. It’s one of the easiest places in Bangkok to satisfy a sudden dim sum craving without a booking.

Loong Foong delivers a polished hotel setting with a robust all-you-can-eat dim sum lineup, and crucially, it’s known to accommodate walk-ins. The room is spacious, queues are organized, and turnover is steady, which keeps wait times reasonable even on busy weekends. Beyond the steamed hits, look for rice rolls with prawns, XO turnip cake, baked char siu puffs, and fried selections that arrive crisp and hot. Service is attentive without being fussy, and the kitchen paces orders well so your table stays topped with fresh baskets. Come slightly before noon or after 2 pm to maximize your chance of near-instant seating. Parking is easy, the MRT is close, and prices are solid for the quality, making it a reliable pick when reservations elsewhere are impossible.

For walk-in friendly dim sum with views, Silver Waves is a top riverside bet. The large dining room and efficient seating system mean you can often be accommodated without a reservation, especially on weekdays or slightly off-peak lunch times. The buffet emphasizes well-executed classics, from juicy prawn dumplings and siu mai to rice rolls, baked buns, and sweets like mango pudding and egg tarts. Service is swift, plates are cleared quickly, and hot baskets arrive in succession so the pace of your meal never lags. Factor in easy parking and scenic Chao Phraya vistas, and you’ve got a dependable fallback when inner-city favorites are full. Do confirm last-order cutoffs and whether tea is included in the package before you sit.

Liu’s dim sum buffet leans premium, with polished service and refined bites in a calm, contemporary dining room. While weekend peaks can be lively, weekdays are typically walk-in friendly, and even on busy days the front desk manages queues well for last-minute diners. Expect skillfully made classics alongside modern touches, like delicate prawn dumplings, steamed spare ribs with black beans, char siu pastry puffs, and molten custard buns, plus soups and simple wok dishes, depending on the promotion. Portions are paced to stay hot and fresh, and tea selections are well curated. Prices sit higher than Ratchada stalwarts, but so does the ambiance and ingredient quality. Arrive around opening for lunch to reduce any wait and secure a comfortable seating window.

A Nana-area institution, Sui Sian pairs traditional Cantonese flavors with a popular all-you-can-eat dim sum format. The dining room is sizable and well-drilled, so walk-ins can usually be accommodated with manageable waits, especially if you aim for early lunch or a later window after the peak. The selection covers the essentials, from har gow and siu mai to rice rolls, steamed buns, and deep-fried favorites, plus simple desserts to wrap things up. Consistency is the appeal here: baskets arrive piping hot, the pacing is steady, and service teams keep the table moving without pressure. Prices are mid-to-premium, reflecting the central location and hotel polish. It’s a strong central fallback when smaller downtown spots are fully booked.
