We tried this on the recommendation of others and were not disappointed. Food and service were very good. We both had pad thai with chicken and tofu.
I would add that this block of Larkin is a bit sketchy at night (and probably during the day as well). In fact, we overlooked the restaurant in our preoccupation with being on alert, and backtracked to find it. We took the bus from Union Square which is easy, and proceeded to a play from dinner.
At an early dinner hour, the restaurant was full. Enjoy!
