Restaurants for a 50 lira meal about 5 lira £2. There are no hard fast rules, regarding tips. There was just the 2 of us. I know different countrys have a rule such as 10% or 20% of the bill. However I know no rule in Turkey. I tip for a great service plus the place's we go to eat ends up about 3 or 4 times in our holiday. No service charge is normal in Icmeler. But I guess my tip would be, go what you feel happy with jwynne.
Have a great holiday and enjoy every moment.
