The king of downtown burger joints sports a crown of shiny hubcaps. "Welcome to Hubcap Grill" reads a sign in the entranceway, "hand-formed, crafted, burgers, never frozen, 100% fresh ground chuck with homemade toasted buns." The tiny burger joint is located on Prairie Street next to the Alden Hotel. There are a couple of tables and a long skinny counter inside the urban snack shack, a few more tables on the sidewalk out front, and a patio with five or six umbrella tables along the side of the building. The muffuletta burger and the Greek burger are fascinating variations on the all-American hamburger. This location on W. 19th street is a better version of the one on Prairie.
