The Travelin Man
You’d be missing out. The burger at Peter Lugar’s was rated as one of the 20 burgers you need to eat before you die by GQ (not always my source for food recs, but this worked). I was skeptical, but it may well have been the best dang burger I have ever eaten in a restaurant.
Lugar’s is VERY pricey for dinner (steaks), but going for burgers for lunch can give you a very clear picture of the Lugar’s experience (and yes, it is an experience) for about 1/4th the price.
