I paid $10 for a pint of Guinness when I was in Vegas once. I was at a convention, and had some down time, so I wandered around playing tourist. I went into one of the casinos, and saw that lovely tap behind the bar, so I ordered one without bothering to ask prices. OUCH! I also paid $20(maybe $25) for a glass of the Macallan 18 yr. old.
