Ha lot's of michiganders here. Funny. Yes buddy's pizza is the best! And so is hopcat! Though it's ridiculous how they renamed the fries. They used to be called crack fries and people (not really people some pc swj apparently cus fox news interviewed a bunch of people and they all said it was fine) thought that was offensive so they renamed them to cosmic fries.
Five guys fries suck. They're all mushy and limp. The best place for fries is Penn Station. They are super crispy, fresh cut fries with the skin on. Amazing.
Food is one of those things where I never have a favorite cus I like all types of food and it just depends on my mood. But some great fast food/fast casual chains are Penn Station, Pei Wei, QDoba (kicks chipotle's butt), Taco Bell, Jet's pizza, Cottage inn pizza. We also have tons of Coney Island's around here which are great diner type food but with some greek stuff thrown in. I like Arby's too for fast food. We don't have chic fil a or popeyes around here sadly.
For chain sit down places I love On the Border, PF Changs, Carabbas (way better than olive garden), Cheesecake Factory, Red Robin.
Some of the better not chains or small chains, we have a place called Steve and Rocky's that has fantastic food with a rotating menu. It's like fine dining american style- fish, chops, pastas. One time they had frog legs. Bonefish is quite good too, I think it might be a chain. There's a place called Palate that's fantastic, a lot of foodie type stuff like chicken and waffle sandwiches, cheese and meat boards. My favorite bbq place is Pappy's in St Louis. It's just amazing melt in your mouth bbq. There are some decent bbq places here like Smoke Street and Kensington Grill, but no where near the level of Pappys.
I'm near a large Indian population and middle eastern population so I'm spoiled with those foods as well, just a lot of great local Indian and Lebanese/Mediterranean food joints.
