Jim's polish is (or at least used to be) a Slotkowski-brand polish. Yum.
Back to Hot Dogs... North Side edition
Wolfie's is pretty good, as is Fluky's. I used to be partial to Poochie's, but that's because they had a more well-rounded menu. But Harvey sold out several years ago and it's just not the same. I was never a fan of Michael's up in Highland Park. When I was a kid, Irving's For Red Hot Lovers in its prime was tough to beat, but they overexpanded into franchises and it all fell apart. The original Wilmette location is still there, but like Poochie's it's a shell of its former self.
I used to like Duke's over near Ridge/Hollywood, but I don't think they still exist.
A good Loop hot dog is hard to find. Gold Coast has gone way down, and their 2 N. Riverside location was sold to an independent.
In DuPage County, a good hot dog is hard to find. Teddy's is the local vendor in my area, and it's completely pedestrian. Portillo's has the most consistent dog, especially the jumbo dog, but it's somehow lacking that greasy independent feel that a good hot dog needs.
