Choose how many stars you want your meal to have; the more stars, the hotter the heat! It's hard to skip out on a sweet Thai iced tea or coffee while you're there to compliment the fire. Also, they have one of the best burritos in town that is so big it will probably last you more than one meal.
Recommended: Gang Panang, Waterfall Salad (spicy!), Big Fat Burrito, or if you're nursing a hangover, try the drunken noodle :).
