Absolutely! To start a tab, simply give your bartender a credit or debit card. You have the option to use either tickets or wristbands to easily communicate with the bartender who is in your group and therefore, on your tab.
If you have a strict budget, tickets are best as they give you control by limiting the number of beers put on your tab. When you do have a budget range, wristbands can quickly identify who is included on your tab.
