I would say overall it wasn't bad value for money. Lira currently 2.3 = £1.
We're just back from Side, stayed at the Arum on a B&B basis.
Out and about a steak will be around 25 lira at most, pizzas are around 10 lira, various Turkish style kebabs and whatnot around 10 to 14 lira.
A pint was normally 4 lira, so under £2, although our hotel was 5 lira for 300ml (so we didn't drink much there), and the mountain top restaurant in Antalya tried to charge us 10 lira for 400ml

for which they got told to do one.
Generally I'd say still a much cheaper bet than somewhere Euro based which is why we went.
