It does all depend on which resort you go to. Some of the islands are more expensive than others.

When I was on the mainland in September the price of a beer (in a bar/taverna) was either 2 or 2.5 euro, it was a lot cheaper at the supermarket but not sure how much.
House wine by the litre was between 4 & 8 euro depending on which taverna we were in. There wasn't a great deal of difference in taste and I found them all very pleasant.

The average meal (2 starters, 2 mains, 2 covers + drinks) was around 30 euro, a little more if we ate on the beach. In the local grill house we could eat for about 22 euros.

A lot cheaper than anything in England.

Yes, those prices are similar to what we paid this year in the Peloponnese. Local wine I don't think we ever paid more than 6euros a litre.
If you eat in less touristy villages prices are much better. We found things a bit more expensive this year ie: main courses all seemed to be 8 or more euros, even a pork chop, which was a bit of a shock.

Hi Nick & Chris - welcome!!!!

Like everyone says - it depends on resort and taverna/restaurant. On Patmos last week, prices for fish were very low (unusual for Greece) and we paid between 20 and 30 euros for a meal including a bottle (75cl) or a loose litre of retsina. The 30 euro meal consisted of prawns, taramasalata, squid, whitebait (as a starter) then seafood souvlaki (octopus, crevettes, scallops) and one other dish I can't remember!!! I do remember not being able to move afterwards.

Lunches were costing 10-12 euros - 2 veggie dishes (stuffed potatoes, briam) and a half litre retsina.

A Mythos beer came in at 2-2.5 euro except in the gyros joint where it was 3.

Back in Kos Town - beer 2 euros, large gyro 3.5....and two blow outs at the Stadium fine dining restaurant (and oh boy was it good!!!) came out at 50 and 55 euros including a very nice bottle of Makedonikos rose each time.

Coffees generally came in at about 2 -2.5 euros.

Never went for starters, by the time you eat the bread they serve when you arrive thats more than enough, average meal would cost approx €5-8, desserts €3-5 and beers €2 - €2.50 and spirits very cheap too but remember that they dont actually measure so you get you moneys worth
