Ray’s Hell-Burger, 1713 Wilson Blvd., Arlington, VA, 703-841-0001, open for lunch only on weekends, I believe 5 p.m. dinner on weekdays. (Metro Trip Planner – opens in new window) [Washingtonian | WaPo | menuism | Don Rockwell | Yelp]
Update February 2013: CLOSED
All they have is hamburgers and they don’t even have a side of French fries (you can get corn on the cob or potato chip or potato salad). It’s the best hamburger around by an order of magnitude. Yes, it is worth paying a $4 or $5 supplement for the specialty cheeses on the cheeseburger. I like the Amish cheddar but consider the Epoisses as well. The quality of the burger and the cheese here really just stunned me. By 12:15 on a Saturday the place is already chaos but somehow it seems to work. Order your burger at the counter and then be prepared to stand at a table (of sorts) and eat it. Not a place to sit and chat but who needs social pleasantries when the burger is so good? The ice cream is first-rate as well.
Update February, 2009: Ray’s Hell-Burger is still at 1713 Wilson, but Ray’s the Steaks has moved a few blocks west to 2300 Wilson Blvd., Arlington, VA, 703-841-7297. They take reservations at the new location.
