I like this. The staff aren't particularly enthusiastic, but they're efficient. Everything is fast, cheap, and quite delicious. You won't be disappointed by the food, but the seating is a little cramped.
The congee is roughly the size of 2 individual bowls. Everyone eats pretty fast and by the pace of the business, it isn't a place to sit around and chat.
Definitely worth trying out, no real complaints except for the fact that the bowls felt like they weren't super clean.
