1. Szechuan First
It's a bit of a drive, but Szechuan First (in Kent a few blocks from Ikea) is worth it. This place is seriously authentic and insanely good. Their Dan Dan noodles are mouth-blisteringly hot, the cracked chili crab is revelatory, and the dry-fried green beans might be the best vegetable side in the state.
