Was on Mardi Gras last month. You get 15 seconds from the time your card is accepted to complete your soda pour. The maximum dispensed each time is 16oz. They had Pepsi, Diet Pepsi, Starry (Sierra Mist), Mountain Dew, Diet Mountain Dew, Orange Crush, and Mug Root Beer (although Root Beer was not available at the Guy's Pig and Anchor location). There are 3 stations in the buffet and one in Guy's Pig and Anchor. It is a far, far better system than having to wait at a bar for soda (except for the places where you get get an entire cold can - like the Pizza Place). It took me about a day to get really good at the timing, and by the end of the week I was a pro (knowing exactly how much ice to have in my cup, etc.).
