Park Slope’s burger boom...and bust

Bonnie's Grill: Gimmick

Bonnie's is the old standby. This classically styled diner is sidled up against Blue Ribbon Sushi and has a downright simple menu. Their burger options are even simpler: a single sirloin burger. Sure, you have your choice of sides, but there's no messing around here. The waiters move fast, and the line cooks work at a near blur. Of course, this all means nothing if this Slope classic can't fend off the eager newcomers.
