Baltimore's traveling food-truck rally has found a winter home -- inside the Gameday Warehouse, a 2,500-square-foot facility near M&T Bank Stadium that is normally only open on Ravens home games.

The first Gathering Underground on Dec. 13 is being billed as a preview party for a planned schedule of monthly winter rallies. The family-friendly event will include a coffee bar, a cupcake bar and beer and wine for sale, as well as live music, a disc jockey and vendors from Bmore Flea, Baltimore's new Saturday flea market at Penn Station.

Gameday Warehouse is at 1400 Warner St. B, across from the LOT J at M&T Bank Stadium

Admission to the preview party is $10.
