Once you get over the fact that you just waited an hour to sit down for a burger, you will appreciate Au Cheval for what it is: an ideal spot for a gathering with friends. This cheery, contemporary diner offers booths roomy enough for eight people, and you’ll appreciate the elbow room once the food arrives. You and your crew will be feeling the groove as you nod your heads in unison to old-school hip-hop, soul, and rock, cranked out effortlessly from vintage reel-to-reel equipment. About that burger? It’s simple enough, but griddled to perfection, with a generous two patties and American cheese when you order a “single,” and three patties when you order a “double.” Got that? Also popular is the stacked, Dagwood-style fried bologna sandwich that will take you back to the days when Mom packed your lunchbox. It’s so massive that you could slice it up and share it among your table. The bar specializes in classic cocktails, so order something appropriately old school. Your whiskey-lovin’ pals will appreciate the attention to detail put into the Old Fashioned, while the more adventurous types in the circle might indulge in a gin-based Pegu Club. The kitchen stays open late, so you can pair your drinks with more food, should this turn into a late night.
