Fail. No mix in the Jewish aisle. All kinds of other weirdness, but no falafel.
It really demands good pita bread, which can be a bit hard to find. I hate the packaged stuff you find typically in the DC area, it all seems to be a bit stale which is a flavor off-note I detect readily.
I'd much rather pay premium prices to Moby Dick to get their fresh made bread, to complement my own falafel.
