I've stopped into the Healthy Greek once in a while in the past, and usually found their food to be passable, though fairly overpriced.
After spending the past 4 days recovering from the food poisoning that I and my friends received from eating their chicken shawarma (the only meal we all had in common), however, I will never, ever return.
I seriously question their food handling practices... your mileage may vary, but if you eat here, beware!
