I can only echo what others have said about their amazing menu. Every possible combination of Thai, Laotian and Vietnamese food must be available here. Amazing! Despite the variety I generally stick with vegetables and tofu in a ginger sauce. Yum! Hubby isn't much of an adventure eater but has taken a few chances here and has never been disappointed.
I have only been disappointed when I didn't know what I was ordering and didn't take the time to ask questions. I once ordered and entrée that sounded delicious and had "gà" in the description. I had no idea what "gà" was but wasn't too concerned because I'm not a particularly picky eater. Turns out it was chicken which I don't care for in Asian food. But I'm not the type to send food back because of my error so I still ate it and it was fine.
Couple things to keep in mind when going here -- you have to go early to have any chance of getting a table. If you have to wait this isn't much of an issue on a nice summer day when you can wait outside and do some people watching on Willy Street. In winter everyone is smashed inside which can also make it difficult to pay your bill or pick up carry-out trying to navigate around all the people waiting for their tables.
Another point to be aware of, it is quite loud in there. We found ourselves having to repeat what we were saying to our dinner mates which got old quickly. Unsure if the building has poor acoustics or just the fact that every table is filled.
