I have been in Cortez several times and it was very nice every time!
The drinks are good, the waiters are friendly (when we were there, there was always only one waiter, but he managed it quite well and we never had to wait too long). The prices are okay, too, and I really enjoy the atmosphere and the couches they have there for sitting (they also have regular tables with chairs). I would recommend anybody to go there who wants to have a nice and relaxing evening. The only disadvantage: you can only get food until 9pm, which is inconvenient for me, but probably no problem for other people.
