Had an outstanding meal (ambience, service, food, decor, the whole bit) at Taste/Paradise, 48/49 Mosque Street in Chinatown, last August. This ain't just a visitor speaking: we were taken by two locals who had been there before more than once. If it's still open and under the same management it has my recommendation. (It's been six months, these things can change, but since I'll be back in late May I hope they haven't.)
