FOLSOM, Penn. — On the same suburban block in a town west of Philadelphia there are two joints that specialize in old-time burgers. The first, with checkerboard patterns and lacquered red seats, aims to re-create the food and feel of the 1950s. The second is a spare, white-painted shack with no room for a fryer. Charlie’s Hamburgers has churned out burgers since 1935. It’s a living relic of the ’50s.
This isn’t the place to come for a burger topped with an egg or grilled ramps, for burgers served on brioche, or fashioned from high-grade beef. What’s surprising about Charlie’s is not that Steve McDonald, the fourth and current owner of Charlie’s, stays true to the recipe and philosophy of founder Charles “Charlie” Convery. . .
