While the Philadelphia location of burger outpost Wahlburgers is under construction at the Rialto at the Piazza in Northern Liberties, its food truck has been set up outside on weekends.

Starting Jan. 21, Mark, Donnie and Paul Wahlberg's grub will be available for online ordering and delivery through GrubHub.

Delivery of Wahlburgers sandwiches, such as Our Burger, Alma's Favorite Chicken and the Portabello Mushroom Cap, will be available during the truck's hours of operation.

The truck, of course, won't be making deliveries - some guy or gal working for GrubHub will.

As for the projected opening of the actual restaurant, a rep is still saying "winter," which does end March 19.
