First note: "This place is very, very expensive". For a turkey sandwich and a slice of cake, you're looking to spend around $35 dollars. While I do appreciate the fact that they are open very late and are a somewhat cheaper alternative to room service, I'd like to point out the fact that their food is extremely over-priced.
During my last outing to Las Vegas, I decided to try this place out. I got a turkey sandwich ($27 with cheese, lettuce, tomato and onions) and a slice of cake. When I asked for mustard and mayo on the sandwich, I was immediately told that it would be on the side. Now, I know this may make me seem like an a**hole, but when I'm dropping close to 30 bucks for a sandwich, the least that you can do is spread the mustard and mayo on the bloody thing for me, not give me a bunch of packs.
The sandwich itself was waaaaay too large. I understand how alluring the 12 inch high sandwich could be, but in reality a sandwich that tall is just too big to eat. After being unable to bite into the sandwich, I found myself in my room having to break it down into sections and unfortunately I only had 2 pieces of bread for about 2lbs of turkey.
My suggestion would be to simply make the sandwiches smaller and charge a lesser price. I know that some people would like the idea of splitting one, but the problem is that you only get 2 small slices of bread and a couple of pounds of meat.
