In Crete, snails are part of traditional Greek food. If you find yourself presented with a plate of snails, here's how to eat them. Clutching a snail firmly with one hand, poke a hole in the top of the shell with your fork. Then suck at the larger opening, opening and closing the small hole, until the snail meat pops into your mouth.

Expect to pay a cover charge at traditional Greek food restaurants. This is the charge used to pay for your linen, cutlery, and bread. But don't worry: the cover charge is usually less than a dollar, and it may be less, depending upon the daily Euro/dollar exchange rate.

Tipping is a bit of a sensitive issue in Greek food restaurants (in Greece at least). A service charge of 15-20% is usually added to the check in any case, so you need not tip. However, it's traditional to leave any change left over from the bill on the table.
