I straighten my hair every morning to glossy perfection. So, whenever it rains, I usually prefer to stay inside. Where it’s dry.

But last night I decided to venture out in the Prospect Heights vicinity toward Dutch Boy Burger — or, as I call it, “That place with the bourbon milkshakes.”

Because, if one thing’s going to get me out in the rain, it’s bourbon milkshakes.

Said milkshakes arrived shortly after the food, but they quickly stole the show. Featuring smooth vanilla ice cream (Blue Marble!) and a spicy hint of bourbon, my Dutch Boy shake was a palatable experience I will not soon forget.

What else is there to say? The veggie burgers are good (and better than their meaty counterparts). The Caesar salad — spelled “Ceasar” on my receipt — is a perfect B-. As for me, my flats and lower pants were soaked, my hair de-glossed to tragic degrees. The Dutch Boy’s front doors remained illogically wide open, turning a chilly experience into an even chillier one.

But you know what? It was worth it. That was some milkshake, after all.

Formerly a Dutch boy-themed paint shop, Dutch Boy Burger is located at 766 Franklin Ave., accessible via the 2,3,4, and 5 trains, and the ever-resilient Franklin Avenue shuttle.
