If they’re that close, go to both. Share a sammich at each place 😉
Hot, sweet, dipped. Maybe even a combo with Italian sausage. Portillo’s has good hot dogs and burgers too, but Al’s is better in my opinion. Italian beefs are easily my second favorite sammich, only after a roast pork w/broccoli rabe in Philly. I’ve resorted to making ghetto versions at home.
I know Chicagoans aren’t big on deep dish pizza, but I’d never go to Chicago without stopping at Giordano’s. Their spinach stuffed pizza is amazing.
Another cool place to go is where they make the pizzas pot pies. It’s just so different and fun. I think it’s called The Oven Grinder Co, but I’m sure someone here can correct me.
