Need a free milkshake today? Larkburger’s got you.

It’s the 10th birthday of Larkburger, the little Colorado burger-and-salad chain that could. That means you get a free milkshake just for showing up.

It’s the 10th birthday of Larkburger, the little Colorado burger-and-salad chain that could. That means you get a free milkshake just for showing up. I normally don’t go for this kind of promotion, but I am partial to rainbow sprinkles, and so I thought I would share it with you.

All you have to do is show up at a Larkburger. The ones on California Street and in Wash Park open at 11 a.m., which is a perfectly acceptable time to eat (drink?) a milkshake.

Also, Larkburger has a kind of interesting story. They were poised for major growth, but they’re still smaller than you might expect because of some early mistakes, as I reported in a previous life.
