Depends on what time you go. During the day Spinnaker, La Vela, and a few other bars have an all you can drink draft beer for $20 or so. That usually lasts until 4pm or so. At night most places charge anywhere from $3 to $5 for a beer depending on what brand you're drinking. I can't remeber if it is actually $1 that you save per beer, it might be a little less or a little more.

BTW the VIP card I'm posting about is only good at Spinnaker.
