I'm trying to think where you could get chili crab.

There's a Malaysian restaurant in Centreville that's really good (Malaysian Kopitiam) but I just looked on the menu and they don't have it. The owners are really sweet and I bet if you called and asked where you could get it they would tell you a place.

Taipei Cafe in Rockville has (or had) stinky tofu. I love stinky tofu. I used to live in Hong Kong and would go to the street stalls in Mong Kok (neighborhood with a lot of markets and street food) to eat it regularly. Doesn't taste anything like it smells. I've never had the Taiwanese version of it but I hear it is better than the HK version.
