This is rather last minute but we are going to Boston tomorrow for an appointment and we'll be near Chintown. We thought it would be an opportunity to get some good, authentic chinese food, since here in Portland, ME this is impossible. Problem is that we will be eating on the late side, around 2:30 or 3 and I'm not sure (a) what would be a good choice, and (b) what is open at that time for lunch. Since we are pretty deprived of Chinese food given where we live now, we are open to suggestions, regardless of the regional origins of the food (szechuan, cantonese, or whatever). We are not afraid of spice or heat, either. Any thoughts?
