Falafel is one of the best I've had. The Union Square location is always very clean and the non-GF toppings are all to one side, limiting cross contamination... though I don't touch the closer dishes. The 7th ave location was a nightmare though. Gluten in all the bins! Still, you can order the specialty toppings for the salad bowl and pay a little extra and never have to hit the "serve yourself" bits.
