The business seats were modern and comfortable. I felt the meals were rushed; didn't finish the salad before they brought dinner; and didn't get offered a glass of wine during dinner, and asked about desert before finishing dinner. Meal was not a relaxing experience. The entertainment on monitor locked up several times while watching a movie; my wife had same experience watching a t.v. show.

Veggie Food was unimaginative and tasteless, and dry. What was that its dish? Whatever it was, it was congealed and unappealing. Apart from Belfast, the movie selection was old.
