mmm ... for plain and simple gyros and fries, i think Athens in Bethany is really good. The meat is more moist and flavorful and I think the cost is a little less too (though they did just raise their prices, but who hasn't lately).

For full-featured Mediterranean fare, I like Cous Cous Cafe and also Mediterranean Deli and Imports, both on May Ave, not far from Zorba's.
