They'll serve burgers and local concretes, including the Cold Shot, consisting of vanilla custard, chocolate custard, malt, salted caramel, dark brown sugar and chocolate toffee. The official grand opening is January 26, but as a prelude, on Saturday, January 18, they'll host a party from 11 am-6 pm, with radio stations, gift cards, and Shiner beer. Dunkin', the doughnut and coffee chain from New England, opened a new location in far north Fort Worth at 5144 Golden Triangle Blvd., right between I-35W and North Main Street on Saturday, January 11. There's not much out there yet but if you're commuting from Keller, the shop has a drive-thru for morning coffee needs (or late-night doughnuts, if that's how you roll). It's located at the intersection of Park Vista Boulevard, off what they call a "roundabout" here, but if you were in Dunkin's New England home turf, you'd call it a "rotary."
