Sumo Bao Bao is a takeaway bao stall on the basement level of Katong Shopping Center at 865 Mountbatten Road in Singapore, and it carries a 4.8 rating on Google.
A good bao stall lives and dies by its steamer. The best buns come off in small batches through the day, with skin that is pillowy and faintly sweet rather than dense or floury, and a filling that stays generous to the last bite. Regulars time their visit to the steam: when a fresh tray goes up, that is the moment to buy, and the popular fillings can be gone long before the day ends. Buns travel well, but they are at their best eaten warm, and a quick re-steam at home beats a microwave every time.
Down among Katong's basement food stalls, Sumo Bao Bao is a handy warm stop for anyone in Singapore's east.
