Grow up in suburbs > Attend Big Ten University (not Illiinois) > Move to Lincoln Park. A most common path, mine included. For many being 22 years old in Lincoln Park is an easy progression from college. Instead of class you have work, and it's even more acceptable to spend everything on booze because it's your money and not your parents. This leads to actually more late-night eating then college because you have to "coat your stomach to sober up for the 8 a.m. sales meeting tomorrow".
From that leads to the options - TBX for a burrito. Awful pizza places on Lincoln for slices. El Presidente if you want to be waited on. Allende if heading to the gf's place. Taco Burrito House if heading home. The Vu for big glasses of Crown. Nookies for breakfast food. Greek place at Lincoln and Halsted for gyros. Wiener Circle for good dogs, huge orders of fries, all covered (with an extra side) of Merkts Cheddar (it's been five years I remember it being Merkt's correct me if I'm wrong). And some sass. Some stupid game that everyone is involved in. It's an adult version of Ed Debevics. Some people really enjoy it. I personally remember just enjoying the food, which is pretty good.
Actually wouldn't be a bad nomination for a GNR. It has longevity, almost an institution. It does something very well that doesn't much exist in it's neighborhood (I'd call it the best dog stand in LP). Uses high quality ingredients, Vienna. Has good functional service. Has character. The neighborhood would be at a loss without it. The beat up picnic tables, flickering menu board, parking in the back, makes it pretty kick ass. The fact that they have to put on a "show" three hours a night to pay the rent in that neighborhood, understandable.
