The food was very good. They had Turkish appetizers and lots of other small items that were great to experience. The crew was very nice and responsive. The Business Class seats were comfortable and they lay flat for sleeping. I am 6'2", 155 lbs, and they were long enough for me, but taller, heavier people might have more difficulty fitting.
