I was at Sichuan Gourmet in Billerica the other day, and tried the spicy chicken wing appetizer. These are GREAT. Hot, tender, juicy, well-seasoned wings with thin rings of hot green pepper and just enough red chili oil to lick off your fingers without weighing things down. I was planning to only eat one piece of the S.O.'s order (usually not a problem), but it quickly turned into a heads-down Serious Eating Occasion. The rest of the meal was pretty tasty too.
The wings are on the Sichuan specialities side of the menu (I think, for some reason they are not listed on the take out menu). They have regular, i.e. non-spicy, ones too but I haven't tried them.
