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!

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

The location is great for conventions at the Hilton. The waitress recommended the garlic fish dish. It was very good. You'd better like garlic, though!

This is a genuinely authentic Thai restaurant! My colleague and I were looking for Thai food, and were thinking to go to a fancy Thai restaurant on zagat. On the way, we found this restaurant. Didn't look fancy, but the menu looked legit. We went in, and was pleasantly surprised. I ordered mango sauce scallops. The scallops were cooked perfectly,... More

Visited twice with family, for lunch and dinner. Authentic, good quality, tasty and delicious thai food prepared by thai chefs. Red and green curries, tom yum, pad thai, prawn/fish cakes were good. Service was ok. Good place to satisfy craving for delicious authentic thai food.

Good food. Worth a visit. Tried the garlic prawns. They are huge and garlic fragrant. Good serving of baby scallops in seafood Tom yam soup.
