I'll also bring

So apparently Marcel used to make a burger, not sure if they were once open for lunch or what. I'd been to Little Sparrow previously and my wife put her name on the mailing list. So one Saturday, Little Sparrow did a "Marcel Burger" pop-up for lunch, limited menu, just burgers, fries, and shakes.
My wife was sick that day, so I went on my own. At one point I was talking with my waiter, telling him how great it was, and that my wife told me about the pop-up but was sick and couldn't make it.
The waiter brought me a take-out burger and fries, comped. Amazing service and thoughtfulness. Love that place.
