They will charge more than what the price on the menu says. Expect to pay 30-50 percent more due to "old menus". We ordered long island iced and a beer. The bartender was even trying to hide the bill when paying. I have lived in Guatemala for years and haven't encountered this anywhere else. They also did not give us the receipt ( only the POS receipt) which is illegal according to SAT in Guatemala (they clearly did not want us to see the prices and we may report them for this.) There are plenty of honest bars in Antigua, walk a block and you'll find a better one. I don't usually write bad reviews, but I can't stand places that have the audacity to take advantage of tourists. Antigua is a great place, don't let this bar bring down your vacation.
