2007 Best Burger

R.F. O’Sullivan & Son

It’s the simplest tasks that often get botched worst—hence the surfeit of humble hamburgers served up dry, tough, and tasteless. The cooks at R. F. O’Sullivan are the most reliable we’ve found when it comes to doing justice to the iconic minced-meat sandwich. There’s the soft bun, the gooey melted cheese, and, most important, the salty ground sirloin that oozes flavorful juices from the first, sloppy bite. It’s a rare (and/or well-done) culinary feat.
