Thai E-San has been an incredibly good experience every time that I've been there (20-30x). The wait people and managers are efficient and helpful, you can get the food as mild of hot as you'd like. My favorite is #51, Eggplant with garlic and vegetables. I like it over the brown rice, it makes for a nice, chewy texture.
They have good beer choices, as well as sake. There are big tables for groups, so bring your friends!
