Full disclosure - I'm picky about my Thai food. Not just because I've had the real deal in Thailand but because I have a limited palette for spicy food and certain textures often found in Thai cuisine.
When the server asked what level of spices (nothing, mild, medium, hot) I went with mild on my sweet and sour chicken. I didn't want anything too bland so I figured mild was a pretty safe bet. OMG, wrongo! Yeah, my lips were burning after only a couple bites. I will say, however, that it was mighty tasty and that I did my best to finish a pretty significant chunk of it. I also had a few bites of Mike's Pad Thai which he also ordered mild. His was very slightly less extreme as mine but still had a pretty powerful kick.
Overall, I thought the food was great, despite their interpretation of "mild" heat. I think that by asking for no spice that I would enjoy it even more. My only other complaint would be that I had to flag down our server for water. There were only a couple tables full of people but I felt the server was MIA too often. And every second counts when your mouth is on fire!
