Just found this board, and noticed that there's not much about Iowa, so I thought I'd post about my best Iowa dining experience. Twas at The Brown Bottle, and out of the way Italian place near the river. They serve my husband's "favorite lasagna in the world" - served in an individual baking dish, topped with a slice of prosciutto and lots of cheese.
I had a deliciously spicy red pepper fettucine with a light cream sauce.
Portions are huge, the ambience is nice, and the price were decent. If we could find something similar in Wisconsin, my husband would be one happy camper.
