This is the best value meal in town without a doubt.

4.90 buys you a 5 falafel balls in a pita bread.  Eat the falafels to make space in the pita and then fill it up with fresh salad and sauces and then eat the salad – and refill with salad as many times as you like.  If they don’t have little forks on the counter ask for one (even better, save a plastic one from somewhere and take it with) so you can eat the salad without eating the pita bread.  When you have eventually had enough, eat the rest of the pita!
