Staying at the Union Square Hilton and after a whole day of sightseeing, was pretty tired and want to eat at somewhere close by. Googled for Thai restaurant and this was right across the street. Wanted to go to some place fancier which would be farther to walk, so checked it out anyway. There was a line but wait was... More

The menu is pretty expansive. The larb was good but completely average and frankly a bit bland. The seafood combo stew was OK, but again nothing special. Would I eat there again? Maybe. Didn't try any of the noodle dishes.

I had dinner here with friends on our last night in Frisco. The restaurant is quite simple and not too fancy but the food was awesome. For me I ordered spicy chicken with veggies and steamed rice. It was really delicious. I also sampled my friend's dishes and they were great too. Thumbs up for this restaurant.

While the service was pleasant, the food was far from what I expected for a restaurant rated #90 out of 4300 restaurants in San Francisco. I went with 2 colleagues who were equally as disappointed, in which the presentation of all our food was sub-par, and it did not look fresh. One of the dishes came out cold, and to... More

I ordered take-out from Old Siam on a Saturday night. The Pad Thai with chicken and tofu was fresh and flavorful. I'll probably be back later this week to try some other dishes!

What a great place for Thai Food! This is one of those "hole in the wall" great restaurants you always hear about. From the outside, it doesn't look like much and you'd probably just go past it without a second thought. The inside doesn't look like much either. But, wow! When the food comes you'll forget everything except the heavenly,... More
