I stayed at the Excalibur in march and this is what i tried.
I asked for a Killian red. Waitress told me that they only served bud, coors and miller. I asked for a Heineken and she obliged.
I asked for a grey goose and oj. Waitress told me that they only served smirnoff.
I guess you cant get much at excalibur.
I know right next door your supposed to be able to order better stuff according to this website
