Perhaps the best meal I have ever eaten. Not a cheap meal by any stretch of the imagination, but definitely worth it. Delicious steaks, fantastic service, and a classy ambiance make this a fantastic restaurant.
You'll probably want to make reservations at CUT. We happened to be walking by to eat at different restaurant and just stopped in to see if they had open seats - which they found for us after a few minutes - but I'd imagine that this is not the norm. Collared shirts and nice jeans / slacks are standard wear, but since this is Vegas, there were several people in t-shirts and shorts.
Each table had two waiters to keep us satisfied. They would recommend specific cuts of meat and sides to go with what we were looking for, and not just the most expensive items on the menu. When the meat came out it was on a plate by itself; an impressive reminder of what was the main point of this meal. The sides were scooped out afterward by the waiters onto our plates as they described all of the ingredients that went in to making that dish.
Didn't make it to dessert, but they let us take away some of the food we didn't finish, which made for a delicious snack after a night out.
High Points: Grab two or three friends so you can share side dishes and appetizers. They're delicious, rich, and you'll want to sample all of them, so go with a group and try a bit of each. Even the lesser-priced cuts of meat are still phenomenal; I can only imagine what the Wagyu steaks are like. Try the mac & cheese; it'll blow your mind. Creamed spinach was also very good.
Low Points: Your meal will be over $100 without trying very hard. The corn side dish was nothing remarkable; avoid it in favor of tastier sides.
