Dropped by for lunch on a Saturday. The place was empty when we got there, but a few parties came in after we sat down.
Service was quick and the employees were all very friendly; however, the food itself was pretty meh. I ordered the Chicken Pad See Ew at a 3 star spice level. At other Thai places such as Banana Blossom or Peppermint Thai, 3 stars offers a decent kick, but at High Thai'd, I could barely taste the spice at all. I ended up heaping chili sauce into my dish to compensate, but it still wasn't spicy enough for my taste. Other than the lack of spice, the dish was also a bit too greasy for me and there were only a few pieces of chicken (though the chicken was very juicy and tender).
In short, this place isn't terrible, but there are certainly better Thai places around.
