I've eaten here several times and go for the view only. The best thing to do is to go during the non-busy afternoon times and get appetizers or drinks after the dinner hour and enjoy the view.
If you go for dinner, the view is excellent. Most of the good reviews here say the view is great, but.... But...the awful service always starts when you get off the elevator. The last time I went, I made reservations, which were correctly taken, but as always, we had to wait between 15 and 20 minutes to be seated. Why? We showed up at the time we said we would, the place was not busy...they clearly were not waiting for tables to be cleared.
We had a waiter and a waiter assistant. The assistant worked much harder than the waiter (she had brought us water, bread and chatted with us a bit long before we had any idea who our server was). The service is always, always, without fail always s l o w. If you walk in thinking that because you are spendng $50 or more per person that you are entitled to service better than Denny's, be prepared to be sorely mistaken. Servers were pretty nice this last visit. More often, they range between unfriendly and surly.
The menu is one page and gives you about 6 things to choose from. Be sure and ask what those items are before you go, because odds are you won't see something you can't wait to have.
The food tasted okay, but was overpriced for what it was. I am not a fan of huge portions, but again, when you are paying fairly good money for a meal, you shouldn't leave hungry. Our first question after our food was served was.."where's the rest of it?" Literally, we thought more accompaniments would come, but the side dishes hide under the small portions of meat. The meals can be eaten efficiently...they are over in a few tasty bites.
The view again is great, but you can't help but feel you've been cheated after you pay the bill and leave.
Pros: The view and ONLY the view
Cons: Service, food, portion size
