Very disappointed.
Drove up around 11:30 a.m. on a weekday and it was deserted. Walk in and, based on Yelp reviews, order a couple of snappys -- a sauerkraut and a Chicago (now renamed the Windy City) plus fries and a drink.
Guy overfills the cup with the drink and just swipes the back of his hand over it before giving it to me, so I've got to grab some napkins to wipe it down.
The dogs come out and I see why they've renamed it the Windy City -- they've removed half the toppings. Now it's just neon relish (but not tasting like the real thing), a ton of onions, mustard and three or four sport peppers. Great. The sport peppers they keep -- the one thing most Chicagoans skip -- but they dump the tomatos, pickle spear and celery salt.
The sauerkraut dog is worse. I've never seen two-tone kraut before; don't know why some of it was a darker brown than the rest. But it was just kraut and even more onions and mustard.
The snappys are snappy, but not very tasty. Only when another guy came in while I was eating did I learn that they're the smallest dogs on the menu; the quarter-pounders are all beef and might have been a better choice.
The fries were so-so -- not crispy enough, but not too greasy.
Unless I missed something, they either have no restrooms or have them hidden behind a door with a combination lock.
I would never go back.
