Where Ya At, Matt?Where Ya At, Matt? owner Matthew Lewis is opening a permanent restaurant called Roux at 4201 N. Fremont Ave. in August, according to The Seattle Times. Roux has a big void to fill — diehard fans will recognize the address belonged to the historic Buckaroo Tavern for 72(!) years. The establishment will feature the same Creole cuisine as the popular food truck, including beignets, po’ boys, and gumbo, along with an upgrade: a beer and wine selection.
