I didn't know anything about Korean food before first visiting Chodang Tofu & BBQ, but the food here inspired me to start making kimchi and grilling bulgogi at home. My wife loves tofu, so she gets a different type of tofu soup each time we go. The grilled dishes and the hot stone-bowl rice/egg dish (bibimbap) come from the kitchen sizzling violently, so there's a bit of theater when these dishes are served.
We love the little appetizers, like kimchi and marinated bean sprouts, that accompany the meal. You get the full set of six even if you just order a lunch bowl, and it's more food than I can finish.
The atmosphere is surprisingly pleasant inside given the seedy nature of the exterior and neighborhood (I always wonder why they picked that location; I get nervous leaving my car in back). The interior is clean and orderly with a spare, Asian look that's very appealing. It's easy to imagine you're in a peaceful little family restaurant in Seoul, never mind the potential for gun violence outside.
This is a great place for lunch and groups, just be aware that they are closed on Tuesdays (I learned that lesson the hard way and ended up consoling myself at Elmer's Tacos). Eating here is a must if you live around Chandler and like to try new things (assuming you're not Korean, in which case, try Elmer's).
