Sichuan Garden in Brookline is a one-of-a-kind in the Boston area. The food is truly authentic. I have taken several native Chinese visitors who grew up on Sichuan food and they were all quite impressed. Try the ma po tofu, the Chengdu-style dry fried chicken with three peppers, the tea-smoked duck. If you are really feeling adventurous try the sliced chicken in hot pepper oil appetizer and the tiger-skinned peppers. Ahooa!
