Grandpa's Burger Haven

Hamburger restaurant · Barnum

"This throwback to the roadsides of yesteryear delivers a (very) welcome dose of nostalgia in a “big big bun,” to quote the sign out front: Everyone knows to order a just-greasy-enough large double with a side of onion rings and a shake — and many insist it’s all best savored while sitting in their car in the parking lot." - Camila Navarrette, Josie Sexton, Paul Albani-Burgio, Ruth Tobias
