Sushi O Buffet - Hotpot Sushi and Korean Chicken - Sushi restaurant in Ho Chi Minh City

Sushi O Buffet occupies a spacious open-plan room on Quốc Hương and runs three distinct formats simultaneously: a conveyor belt stocked with sushi, a Korean food buffet, and individual hotpot stations — all at a flat 250,000 VND with no tier upgrades or complicated menu levels to navigate. The deliberate simplicity is part of the appeal; one price, one menu, sit down and eat.

The conveyor belt is the centerpiece, and it ranges wider than most comparable operations in the city. Fish roe nigiri and seaweed nigiri appear alongside the standard rolls, and the selection extends into cuts that rarely make it onto Vietnamese conveyor belts. The buffet line draws almost as much attention: staff restock it continuously and keep the presentation tidy well into the evening, which is a meaningful operational commitment at this price point. A QR code system allows additional item orders after 8 PM.

A novelty element — a reaction-time challenge where diners attempt to stop a digital timer at exactly 7.77 seconds to win one million VND — gives the place a distinct personality that matches its gregarious, crowd-friendly atmosphere. The owner is regularly described in reviews as hands-on and accommodating, particularly with specific dietary requests.

The dining room draws families, large friend groups, and value-focused visitors who would otherwise be priced out of Thao Dien's higher-end Japanese options. With 4,001 Google reviews averaging 4.9 stars, the kitchen satisfies consistently at volume. A minority of later-evening visitors have noted that sushi rice-to-topping ratios can skew heavy and hotpot ingredients lean toward frozen products, so timing matters for those prioritizing ingredient quality over sheer variety.
