As far as bartering is concerned I am not your person as I dont do Shopping as a passtime
The only specific thing I can remember about the cost of eating out is that we were a bit short of cash last year and being 2 adults and 2 hungry teenage boys got to our last night with only 50tl left.
Even with this we still had a very good night, were well fed and I still had enough for a couple of beers next day while waiting for the coach to the airport.
Temp at the moment is high 20s.
See my reply to your Woodland question. Forgot to ask are you there for 1 or 2 weeks.
By the way it's not my rules but you might want to take the caps lock off when using the forum.
