Best burger for me is at Standard Diner in ABQ.
1/2-lb Bourbon-butter burger, as featured on Diners, Drive-Ins, Dives.
Homemade buns, cooked (correctly) to order, drowning in that bourbon maple butter. Side of sweet potato fries to sop up the buttery mess. It's a two-napkin eater, for sure.
Very rich. Can't finish it, but it's good.
