We found ourselves in SF on Folsom after a class on Saturday, and noticed Basil Thai's sign (great graphics).
It was 6:30 when we wandered in, and were seated right away; just a few tables were occupied. There's seating in the front by the window, a great bar in the middle of the space, and a comfortable back room. The decor is modern but not sterile. The only post I found on this place mentioned that it was loud when crowded, but that wasn't a problem at this early hour.
Service was great, starting with some excellent beer on tap served in tall thin glasses that really showed off the color of the beer. We both ordered Amber Boont (sorry about mangling it, but that's what Graham remembers it being called), which had a nice bite to it, and went well with the meal.
Started with porpia sad, fresh rolls of vegetables and tofu served with crushed peanuts, chili and lime vinegrette (that's how they spell it on the website). These were wonderfully fresh, biting into them tasted like summer. Our potstickers were served with a Thai style ginger soy sauce that was addictive....I kept dipping everything on the table into it.
Our main dishes were gai prik khing, crispy sliced chicken and string beans tossed in the wok with kaffir lime leaves and chili, and nuer tai cai, beef cubes stir fried with lemongrass,bell peppers and roasted chile paste. I loved the chicken, the flavors really melded well. The leaves were fried, which gave some depth to the dish. Graham enjoyed the beef, which I thought was the least memorable part of the meal.
The service was attentive without being cloying, and the place had the flavor of a great neighborhood hangout. I wish this was in my neighborhood, I'd definitely be a regular. Bonus points for easy parking (at least when we were there). It's at 1175 Folsom.
