The Home Cooking board is discussing "stuck rice" dishes, and someone asked about Persian restaurants serving this type of dish - specifically, the crust of rice created when cooking a pot of rice.
In Minneapolis, the Caspian Bistro serves Tahdig as an appetizer with either a yogurt or meat sauce. It's delicious, very rich, and there's a lot of it. (Our group of four couldn't finish it.) And it's not always available; there's only one made per pot of rice. But try it if you're there with a group - I'm sure you'll like it!
Their other food is great, too - I especially like the lamb and chicken kebabs, the chicken on rice with barberries, and the lahmajun.

And here's a picture that a visiting eater took of the Tahdig at the Caspian Bistro:
