Chicken Shwarama lunch special is the way to go!!
These guys are really generous with portion...literally 5lbs of food as they pack the container until it's filled to the rim! So I'd recommend getting the small, not large. I sometimes eat the small for lunch AND dinner, it is so much food. You may also ask for salad only, no rice for a lighter meal.
Tips: Go early before 12pm to avoid long line-up or go later but not too late because once they sell out of the shwarama, there's no more (~2pm)!
