Mc to Dubai is probably the place where you can have a relatively "inexpensive" snack. Overall, the impression is good. Clean, the staff works fast, the food is normal (for fast food). It is possible to independently place an order at the express checkout.
It's probably funny, but in Islamic countries I like to go to McDonald's. It doesn't work in Russia because it's not halal, but there's halal and I always like it there. I love McDonald's.
