Rosamunde Sausage Grill’s Tuesday Burger

May is National Hamburger Month and there’s no better place to celebrate this American tradition than at Rosamunde Sausage Grill on Lower Haight.

I went back and forth about sharing this tip. Rosamunde’s Tuesday burger is by no means a secret, a line forms down the block every Tuesday beginning around 11am; however, the burgers are only served until they run out of meat. The more people who know, the faster they run out.

But I figured, what the hell, these burgers are so damned good, it would be a sin not to share. And rather than save the best for last, in a month-long series of exploring San Francisco hamburgers, I thought I might as well get this one out of the way, because if you don’t read another post in this series, this is the burger you should know about.

What makes this burger so good? Maybe it’s the simplicity of it — a thin patty of high-quality beef, with or without a slice of melted cheddar, served on an onion bun with lettuce, tomato, and onion. No frills. But yet this is the best burger I’ve sunk my teeth into in San Francisco, and it’s only $6.

Maybe it’s that the burger is cooked on the same grill top that’s used to cook up the juicy sausages Rosamunde is better known for, the grease from the sausage seeping into the burger patties, adding a wonderful fattiness.

Or maybe it’s the combination of washing the burger down with a couple pints of beer next door at Toronado.

Whatever the case, if you haven’t had the Rosamunde burger you’ve got to give it a try. They’re only served on Tuesdays, so it makes it difficult to get over there if you have a regular 9 to 5, but it just might be worth cashing in a sick day.
