I nominate the BBQ beef salad at Yai (if you ask them to make Thai-style!), the nam prik oom (sp?) at Sri Siam and several dishes at Renu Nakorn. The long-gone, much-missed Sri Lankan restaurant Chamika Catering had a spicy "deviled meat," and Szechuan hotpot never disappoints. I'm trying Chung King for the first time tonight, so I'll probably have new contenders soon. What dishes do YOU count on to pack the heat?
