One of my favorite places to go for Thai food. The service is great, fried spring rolls are amazing and it surpasses my Pad Thai test. My litmus test for any Thai place is to try their Pad Thai and Saks has my favorite yet.
They offer various meat options from the standard beef, pork, chicken, and shrimp. They also have Tofu options as well which are very good.
They work with you if you have gluten intolerance, on one occasion a colleague received a fresh spring roll in lieu of soup or salad as both contain gluten. On the next occasion he did not receive any substitute but we had a new waiter so I'm pretty sure the odds are that they would substitute something if you don't ask but you could probably ask and get a substitute.
