Great little Thai sport whose prices average about 25% less than most Thai restaurants. The food was terrific, sufficiently spicey as other reviewers mentioned and also not as much sugar as in most Thai places, which I assume is more authentic. Tom Kha was nice and citrus-ey with lots of lemon grass and my beef with eggplant main dish was spicy and had a great flavour.
Service (all of the folks seemed to be young people when we were there) was friendly and very pleasant.
As other reviewers mention, ignore the slightly down-at-the heels building - it means nothing.
