BuddhaBA. In the heart of the city's Chinatown, BuddhaBA is part pan-Asian restaurant, part tranquil garden, and part art gallery. The service is understated, but always gracious, and the food is a pleasure to both look at and eat. The tastiest dish on the menu is the paté imperial, a unique twist on the classic Vietnamese banh mi sandwich, reinterpreted as a pair of long, delicate, crispy springrolls. The Chinese sweet-and-sour dishes are always delicious, if sometimes erring a trifle on the sweet side. Finish up with a pot of tea, perhaps out in the garden during nice weather.
