Anything in Vegas that isn't the $2 hotdog special at Circus Circus or maybe, MAYBE fast food (specifically In-N-Out), you are paying about twice as much as you'd pay for similar food in Oklahoma.
I love Vegas. I've gone twice each of the last two years. But it has gotten so expensive that it's almost not fun anymore. Nothing free. Nothing at a discount. Very little at a reasonable price. Fees on top of fees on top of fees. $15/$25 tables is generally the minimum. You can get some free/discounted rooms, but you have to gamble quite a bit and use your rewards card.
They (Vegas) really need to re-evaluate how they are doing things. I think they'd be better off trying to increase the number of visitors by giving back some of the benefits of going to Vegas. Lower the resort fees (or do away with them). A bottle of water shouldn't be $7. I should be able to get a burger for a reasonable price.
