I've been here twice now and both times the food has been mediocre. Last time
I had the red curry with chicken and my friend had the pad Thai with chicken. Both dishes were a bit boring- needed something else.... more spice? Peanuts? Cilantro? ... something. The time before I had the papaya salad, and again it felt like it was missing something.
On the positive- the prices are reasonable and the staff are very pleasant. They've done a great job with the interior, and I think it's a great addition to 4st dining.
