Char dog was good. Cheesy tater tots were garbage. Mac and cheese was nice portion for a small but average at best.

Customer service is weak. Burger meat and fries have no seasoning. Place needs to be remodeled inside.

They've got those classic brownish fries homemade from actual potatoes. Second to none.

My husband and I decided to try this place again for a casual date night and to check this place off our list. We came on a Thursday evening (12/18/25), around 8:15pm
When we came before, the credit card machine was down, so we didn’t get to eat previously.
We ordered a double fatso combo (double cheeseburger, fries, and drink) and a junior cheeseburger which costs around $28. The service was efficient but not particularly friendly.
We decided to stay and eat there. The food was prepared and came out quickly. The burgers were wrapped neatly in the popular silver, wax-lined paper and the fries were in a basket.
The burgers were fresh and hot, and the lettuce and tomato firm and crisp, which I appreciated. The cheese was warm-ish, but not melted so I left it wrapped for a couple extra moments.
We both came to the conclusion that the charred, crispy edges of the burger were the best part. Other than that, the texture and flavor were unremarkable, and slightly reminiscent of BK burgers back in the day, except in a smaller size. The fries were okay, pretty warm but not quite hot, and even once salt and pepper added, still simply meh. The grease may have been old, since there was a bit of an “aftertaste” that was slightly bitter and didn’t quite taste right. Unfortunately, the “Dr. Fatso” (drink) was the best part of our meal.
So…all in all, between the dingy decor and slightly worn atmosphere, the nostalgia of old school burgers and fries as a treat was interrupted not just by the missing flavor and ambiance, but the high prices. I’ve certainly had better burgers of the fast food variety…and in Chicago, there are lots of options all around! From Dillinger’s on the far southside to Au Cheval on the northside, Fatso’s didn’t really rate.
Cool with having the experience, but wouldn’t go back. I’d rather go to the Burger King around the corner instead next time. (At least I’d get pickles and grilled onions lol)

Well done American fare; I liked the char dog that I got. The fries were crispy but still had good potato heft, and the cheese sauce had more depth than typical nacho cheese sauce. I particularly enjoyed the banana shake. It tasted like they had used fresh bananas and did not skimp out. I tasted my friend's cookies and cream shake that had nice bits of cookie.
