A coworker of mine recommended that I try Amano's a while ago and I finally decided to give it a shot.
The first thing to know is that only carry out and delivery are available -- don't try to go in for a sit down meal (inside the building, you'll only find a large kitchen area and a counter).
While there are numerous items on their menu, I decided to try their deep dish pizza. I am not from the Chicago area but I have eaten deep dish pizza from numerous establishments, both in the CU-area and in Chicagoland. I would have to agree that Amano's pizza is better than Papa Del's and certainly on par with pizza from a "real" Chicago pizzeria. Additionally, the prices were extremely reasonable. A medium (12") pizza with 3 toppings was barely over $15 and will provide two meals for my girlfriend and me.
As with all deep dish pizzas, expect to wait a bit for your pie to be ready (ours took about 35 minutes).
The only reason I did not give Amano's 5 stars is because the dough in our pizza was not cooked all the way through in some of the thicker areas. I didn't mind but I would have preferred it to be fully cooked everywhere.
