500 Degrees, the new Sansom Street burger joint from Rouge owners Rob and Maggie Wasserman fires up its griddle today at 11 a.m. and will feature a day full of promotional extravaganzas, including free burgers. The new spot, supervised by Rouge executive chef Matt Zagorski, will serve five-and-a-half-ounce versions of Rouge's signature burgers, which were one of 22 notable burgers featured in our Burger Register. Each burger is griddled to your preferred temperature and can be paired with a taut variety of fries and Bassett's ice cream shakes.
