Jim's is legit amazing. I end up going very rarely but every time I do it's been a perfect diner experience.
I tried their liver and onions (an aquired taste it turns out I don't really have) and a slice of some meregiune pie and idk, it really transported me, the food is always very real tasting, it's hard to isolate what it is that makes so much food taste manufactured now.
It's like Donns Depot, places that connect us to some wholesome parts in our shared history.
I've never had a bad meal there. My favorites are the pancakes and the chicken-fried steak.
