Very good Thai food near Union Square

We found Ar Roi several years ago while in town as tourists - stayed at a Union Square hotel - and loved it. We live here now and finally got around to going back. Stopped in last weekend for lunch and were thrilled to find the same high quality food and thoughtful service that we'd experienced... read more

We made reservations for a special event and called just before we went to verify our reservation. We were told it was cancelled. They booked a private party for that night and no one else could dine. No phone call nor e-mail. I guess money is more important than reputation. Pretty tacky don't you think?

From the very first time I ate here back in the late 90's, this has been my favorite Thai restaurant. We discovered it while visiting SF while staying at a Union Square hotel. We were walking down the street trying to decide between 2 Thai restaurants we had seen. An actor from Phantom of the Opera was walking in front... More

Probably our best value meal in San Francisco. A couple blocks west of Union Square; easy walking distance to many hotels. Authentic Thai food at a good price and in a pleasant and clean environment. Obviously too many tourists as the waitress asked several times about spice level. We assured her we were fine with spicy food and were greatly... More

We had Pad Thai and Spring Rolls -- agreed that it was the best Pad Thai we had ever eaten. While we didn't sample anything else on the menu, judging by the two dishes that we had, I would say this is a really good Thai restaurant.

Ate there last night. Service was very prompt and friendly. Tom Yum soup was a little disappointing as it contained inedible leaves that you had to pull out manually. The entrees were plentiful and tasty although the Pad Thai was somewhat under seasoned. ..it also left me with a raging thirst about 2 hour s later. MSG?

Went there for dinner with two colleagues. Service is fast and good. I had a mild curry and sticky rice (Beef Kang Panang) which was good, one colleague had Choo Chee Pla (Fish) which she did not like much as the fish filet was very hard, the other colleague had BBQ Prawns and Chicken which he liked. Size of the... More

This restaurant was very close to our hotel which was perfect after a long day of walking. The food was excellent and the service good.
