when I was in greece, I hit those little "fast food" gyro places. Chicken meat and fries in a pita! Yum!! I think that was like 4 euros, and that was on Santorini, so I would think it's cheaper on the mainland.
There is NOTHING like Greek Gyros! We have Cyprus Gyros and they aren't the same. Last year a guy from Athens moved in our area and opened up a restaurant. None of them speak English but they know what I want when I call. 3 Double Greek Gyros (Tria Dippli Yeros Ellinika). Some seriously good stuff.
Santorini is a nice place, been there once. Did you take the mule up the hill or the lift?
Re: Reaching your goals. Getting started and your check list for success
This has to be a life style. It's not a part time recreation where you go partying every weekend with hopes that monday your weight be back to where it was on friday.
One mistake people make is believing they'll get discipline in a matter of weeks or less. Discipline is a muscle you have to strenthen every day. Discipline is not wanting to get up to train because is cold, raining, or you're tired, but get up anyway.
I have no time for people who wants to get better, but can't give up partying or can't stop eating junk. You can't have it both ways. It's best to decide what it is you want. Once you make that decision, then do what it takes to achieve it. Simple!
I always go the extra mile for those who really want to improve themselves.
