Best Burgers in Philadelphia | Eater Philly
"River Twice is known for their expansive tasting menu, but the ultimate stand-out from it has been the “mother rucker” burger — chef Randy Rucker’s tantalizing conception that features quarter-pounders of beef layered with a seasoned mayo, cooper sharp, and pickled onions on an exceptional milk bun that can barely hold its greatness. If you just want the burger, go on Monday nights when they’re available a la carte." - Maddy Sweitzer-Lamme
