I stopped in for lunch with a friend after hiking in Thunderbird Park. Located in a strip mall in the Arrowhead area, Pita Kitchen is a tastefully decorated, if somewhat generic, small chain restaurant. You choose food from a menu board then walk up to the counter to order. We both chose the Mediterranean Sampler, which is vegetarian-friendly and offers a little taste of several menu items.
The amount of food on the plate was pretty generous for a sub-ten dollar meal. Everything "looked" like prototypical Mediterranean food, but after tasting each item, I realized it was the fast-food version. The tabbouleh was oversalted, the pita was fluffy and somehow too white. The falafel, baba ganoush, and hummus were all tamer, blander versions of the food I've enjoyed in more heartily ethnic eateries.
The location is convenient and I would eat there again if I was in the area and hungry for a quick bite. Ample parking is available and service was efficient.
