There are several Daphne's locations in San Diego County. I usually eat at the San Marcos, Poway or Mira Mesa locations.
The menu is fast food Greek--think Hummus, Gyros, Falafels, Salads with Feta Cheese and briny Black Olives. There are also vegetarian options as well. The prices are very reasonable (I don't think anything is more than about $9) and the service is quick and friendly. You can also get platters and bulk orders to go for parties or family style service at home.
