Based on previous meals, I have been recommending this restaurant. I was in the area on Friday and went there for an early dinner (around 5:15, leaving just after 6 P.M.). It is an interesting place for people-watching and eavesdropping (that time there were two actors talking about their lives and careers, and a bunch of out-of-town tourists there for pre-theater dinners talking about what they were going to see). As for the food:
The tom yung koong is not as good as in some of the restaurants in the East Village: They use canned rather than fresh mushrooms, with a rather strong canned taste, and the shrimp could have been fresher.
As for the steak salad, the steak was a little fatty and a little gristly, but the dish is still delicious. I finished up with a rather large portion of excellent coconut/pumpkin custard for dessert, which came with slices of orange.
P.S. There is a pretty good new Thai restaurant on Av. A between 6th and 7th Sts. Its menu is limited, but its cooks are good. I've had takeout once and eaten in once. I wasn't blown away with their pad Thai, but their spicy main dishes (e.g. a green curry, and a dish with basil and hot pepper - I forget the Thai names at the moment). And it's open until 1 A.M., 2 on weekends!
