You would think that Greek food would be a natural for casual, take out places.  You can make a lot of the food ahead.  It is good served cold.  Much of it is finger food.  Yet, with the possible exception of some places in Chicago, most of the Greek take out places I have been to are subpar.  Crazy Pita is no exception to this rule.  We ordered a falafel sandwich, a shrimp skewer, and a mezza plate (feta, hummus, artichoke hearts, cucumber salad, and roasted peppers) to share.  As I expected, the shrimp was tough and was sitting on some watery vegetables and undercooked couscous.  But it was the hummus that surprised us the most -- thin, drippy, and tasteless.  The pita served with it was dry.  The roasted peppers had no flavor or texture.  The best things were the cucumber salad and the falafel.  Now I have had better falafel, plumper and spicier, but this at least was crisp, moderately spicy and did not fall apart.  I could only compare this to the delicious hummus, gyros, and stuffed eggplant we had at Max's Greek Cafe in the San Francisco airport.  If you can't serve better food than an airport cafe, then you can't expect to stay in business for very long.
