Let me say right now - this is no health food place. If you're looking for small servings, go elsewhere. If you want huge greek salads, gigantic succulent fish with fresh cut fries, a hungry man's break fast, or other hangover curing fare, then head here if you can make it.
It's a tiny place, and it is not meant to be chic and stylish, and it shows. Disregard any appearance. P And M offers a good range for all age groups, and I have never been unhappy there, and I've been several times. Worth it, if you can find a seat.
