Their concept is simple, they hand you a pita with "just" the falafels inside for $4.00. Then you step to their condiment bar and stuff it with as much of any one or 10 (?) items you want. If you want to stuff it, i.e., full of nothing but humus, you can. Personally, I like this approach as you can truely have it your way; provided they offer the conidents you crave. Some I can remember:
Tomato, Onion, Cucumber
Onion - plus a tad of spice(s)
A salad mixture
Sauces = Humus, Tahina, White, & hot sauce.
They promise to make the falafels while you wait & the pita bread "they" bake. I have been to the Falafel King in Westwood over many years and I find their store bought Pita bread to be poor. Both the falafels and pita are much superior at Bella Pita, unfortunately, I still crave the red chili & green sause(paste) at F.K. and it's my main (or only) reason to return there. Bella has a very limited menu including a Beef Wowshi, which has a rather thin inner coating of ground round, plus a few extras in a larger pocket than a pita (which are both baked together), and you stuff as well. They also have french fries for those who like them inside their pitas (Israeli style?).

No tables, no chairs, just 4 stools along a foot wide counter against the front window. A 2 week old real hole-in-the-wall and they even claim to validate parking in the back.
