Sichuan cuisine seems to have gained popularity in Boston. I guess spicy cuisine is loved by all :) Here are the favorite haunts of Chinese expats in Boston.
Sichuan Garden - The original though not as good these days. They do have a good melon dish that you can't find elsewhere though.
Sichuan Gourmet - My new favorite. 2 locations in Framingham and Billerica. Apparently spun off from the chefs at Sichuan Garden.
Zoe's - Great hole in the wall place in Somerville. Get the "cha su gu" which I haven't seen elsewhere. It's a longish tea mushroom stir fried with pork.
Please leave a comment and let me know of new great Sichuan restaurants or dishes to try!
