It's not easy finding really good falafel, but Princess nails it! I've yet to find one that is better. The veggie options are comparable to those you find at most middle eastern places (hummus, baba ghanoush, dolmades, etc. - all are very delicious!), but, yes, their falafel is the bomb. The only complaint is that the restaurant portion of the market is a bit lacking in atmosphere, but that doesn't really matter when the food is this good. The servers are friendly too! I've since tried other middle eastern places in Tempe, but they don't compare to Princess!
