When I rate a restaurant on a scale of 1-5 I include, service, quality and price.
By far and away Bistro at Palms if the best value in Vegas if you go there for lunch or dinner Sunday to Thursday. Thursday being the best deal if your a senior. Friday and Saturday dinner are pricey for the same menu items available Sunday to Thursday.
As for "Lame, pointless and annoying." there is an express line for the disabled like in all Vegas buffets and most people know there is a discount with the club card.
I am a fan of Bistro Buffet. I think their lunch deal is not only the best in Vegas but probably the best in America.
