I feel a bit odd reviewing a Buffalo Wild Wings, but my foreign friends always want to go when we are in Vegas and we always go to this location.
If you've been to Bdubs before it's pretty standard fair, lots of tvs and wings and other fried foods. The only real difference is this one is open 24 hours, which is nice.
Not surprisingly if you are going here for a big sporting event it will be very busy, especially if it is a UFC fight. You will probably have to get there an hour or more early and/or tip someone heavily to get a seat.
Best things are the mini corn dogs and wings. If you order just those you will have a very pleasant meal. Sauces depend on your taste and spice tolerance but I normally go with Spicy Garlic and Asian Zing.
My two British friends routinely spend 100 dollars between them, so I'm pretty sure if anyone ever decided to open one of these in London it would be like printing money.
