Been here a few times with my husband and a variety of family members. Everyone we bring here loves it--the food is good and simple.
The location, like most of the restaurants in downtown Leesburg, is a bit tight. They do have a shared outdoor eating space with the restaurant next door which is great on nice days.
My hubby and I just took a trip to Chicago last week and I can say without a doubt that these dogs are as authentic to the real thing, but with even better ingredients--you can tell the staff cares about putting out a great product. Great little place for lunch on the weekends--we've had just about everything in the menu (Chicago dogs, cheese dogs, Italian beef) and all of it's good.
A great, inexpensive place to grab a dog and a beer (by the bottle) while you are out and about.
