Yemeksepeti.com is the first and biggest online food delivery portal of Turkey. Last year, they have gone through a design change and got a new logo as far as I know. The new website is easy to use and definitely designed with the best user experience in mind, no doubt about it.
I use them on a weekly basis and love accessing my favorite menus with a couple of clicks, but the time has changed and I am now using my iPhone 4 and iPad 2 to do all the work. So last month, I downloaded their iPhone application and could not help but noticed that its not optimized for retina display and their icon is at a lower resolution even for the iPad.
