Hey!
When will you be there? I'm planning on going there in few weeks as well!
Been to Greece many times before. From my parents's place in Israel, it takes 4 hours by boat to get to Greece
(But most likely I will fly with my sister in law for a little get away)
The beaches will be FULL of Bree'EEsh (That's British) people and topless hotties just so you know
Best food? ANYTHING greek that is not commercial. Stay away from Gyros in the street, unless you see a big line of people.. some of those can be nasty
and ruin your trip with puking... hehe
Try the local Shwarma, and the "greek breakfast style" food.
Tones of veggies and cheese... YUM!
I don't really know about the beer.. nothing that I tried there was "amazing" but the wine is GREAT!
Have fun! Greece is a great summer-vacation.
