A visit to the University of Pennsylvania took us down Walnut Street, where we were looking for some good food, but didn't want a full-on restaurant or burgers.
Mediterranean Café is in a dedicated Food Court which we had walked past several times and missed-- maybe because there's a red awning outside which is just like the CVS Pharmacy awning next door.
We had a fine meal, which for 3 adults came to $31.30, and a variety of food, and plenty of it. The Gyro Combo included Roasted Lamb/Beef Tatziki, Hummus, Bab Ghanuj, lettuce, tomato, and onion. Their falafel was perfectly cooked and light.
They have plenty of vegetarian selections.
In addition, they have a huge selection of smoothies, yogurt, ice cream, fancy cones and ice cream bowls, but I have to say, we didn't get to try them because we were too full already!
