Hong Kui Jia means "Red Armor" in Chinese - not a bad name for a crayfish chain. It has multiple locations around downtown, but expect a long wait at some of their popular locations. Lots of drinking and buzz, a very typical Chinese late-night dining vibe. They have all the crayfish classics, from traditional 13-spices, to Ma La (hot and spicy), but their specialties are "bing zhen", served cold over a bed of dry ice, and salted egg yolk.
