Ugly Baby What is it? Booming on Smith Street in Carroll Gardens since 2017, Ugly Baby is a Thai restaurant that will test the limits of your heat tolerance. Fiery flavors abound in the “stay-away spicy Udon Thani’s duck salad," and orders of soothing tue ka ko will slake any palate flames. Why we love it? Ugly Baby’s use of spice is a master class in heat notable to aficionados and novices alike. Like a lot of the city's best no-reservations restaurants, the wait for tables can be long, and if you don't nab a spot close to 5pm, expect to linger for a while.
