Gyros is probably the best known of Greek cuisine. It consists of meat sliced from a very large roast. It could be beef, lamb or chicken. Restaurants usually serve it on a plate. You will also find takeout stands that serve it in pita bread as a sandwich.
Kalimari is one of the specialties of Greek seafood that you will find on most menus. It is fresh squid that is cut into rings and deep fried. While it may be unusual to the American palette, be brave, you'll love it!
