Top of the World is for sure a tourist destination - but one of the better ones I experienced.
Just so everyone knows - yes the restaurant spins! We went at 8:30 PM and it was dark outside - I feel this would be the best time to sit high above the strip and take in all the lights of the city that never sleeps.
To begin, you have to go through quite a bit of pre-screening before arriving to the restaurant. (After walking through the casino and up an escalator to get to the elevators to go up) so keep that in mind when you're giving yourself time to get to the restaurant.
To begin - YOU MUST if you like chocolate martini's get one. It was delicious. My coworker and I both got a few. Secondly - the bread is "hard" per their direction so don't bite into it expecting fluffy flakes. (This was odd but the butters were delicious so I went with it).
We did the al la carte menu, but there is a chef's tasting menu option as well. I had the 9 oz fiet that was cooked to perfection and we shared the green beans and potato puree sides. And the sides were heavenly. Also we got salads to start - they were much larger than anticipated. Two could easily share one as an appetizer.
Additionally - they have a photographer that goes around and takes photos while you're at dinner. We got suckered into buying one for each of us because we were there for a special occasion (it was my birthday) but normally we wouldn't buy one. The also gave a "free dessert" because of my birthday. It was rather small and one person even called it a "Chocolate fart"....which was funny. But alas, it was small but mighty of a dessert.
Lastly, since we ate at the restaurant they allowed us free entranced to the observation deck. I'm not sure what the cost of that is but it was nice.
Overall, fun experience. Not something super awesome that I would do again - but still fun
