Indiana, from Bloomington north to Michigan, is all one big cornfield... the town is literally the on the invisible dividing line between rolling, green hills and infinite farm space. As you travel south and get closer to the Ohio River Valley, things in Indiana really get scenic, it's beautiful country.
There's like 3 non-chain or all-night diner restaurants in Bloomington, but that's mainly due to IU. Sports (OK, basketball) drags in massive crowds, so plain and familiar tend to be the norm. Any big US college town will be pretty similar. New York or San Diego would change your mind on US cuisine
Glad you enjoyed yourself! Bloomington is a fun place.
