Burgers on the grill

The facade of 500° - at 500 pixels wide.

The Rouge-owned burger shop 500° - on the 1500 block of Sansom Street next to Roy's - is shooting for a March 17 roll-out.

As I reported back in October, owners Rob and Maggie Wasserman were inspired by their burger sales during last year's Rittenhouse Row Festival to open this upscale but budget burger joint.

About 20 people will sit inside; most business will be takeout. 

The interior has been framed out, and electrical work is next.

For now, here's a look at an artist's rendering of the facade.
