Just tried out the new Elevation Burger that opened in the Wynnewood Shopping Center. They're a chain with other stores in Texas and Florida, as well as a handful in NY and NJ. They emphasize grass-fed beef in their burgers, and other "green" aspects.
The burger was quite tasty, I thought: a notch or two better than 5 Guys. Juicy meat, and a good selection of toppings. Excellent fries as well.
Worth a stop if you're looking for a quick bite on the Main Line.
