Recently discovered a little Greek cafe hidden away near South Coast Plaza called The Whole Pita Greek Island Grille.
Not sure how "Greek" it is, but the quality of the food is very high, very fresh, reasonably priced (nothing over $10.00). Staff is very friendly and helpful.
Some menu items include pita sandwiches, taverna platters, and casseroles.
3940 S. Bristol St., on the corner of Bristol and Sunflower, right next to Carl's Jr.
