Swan Thai has a 5 point scale when you order how spicy you want your food. A good indication of how good a Thai place is for me is whether a place has the capability of living up to the spice they claim they put. A lot of times I go to Thai restaurants that ask for medium or spicy, and I get very mild. Usually these are more Americanized type restaurants.
I ordered the larb chicken salad with level 3 spice. I know I might be in Arizona in the summer, but I was eating inside and I was sweating profusely from the top of my head through my nose. The food was quite tasty, but I will be careful and get a level 2 spice next time. Other than the extra spices, I was quite pleased by the tangy flavors of the larb.
All my other coworkers seemed to enjoy their food as well.
