We're coming to Chicago in July from northern California, where suits and ties have all but disappeared from even the best restaurants. Do I need to bring a suit (or jacket and tie) to feel comfortable in restaurants like Alinea, Moto, and Avenues? Will they even let me in without a tie? Remembering what the weather can be like in Chicago in July, I can't even imagine putting on a suit, but I don't want to miss the very creative cuisine at these restaurants and will dress as the Hounds advise.
Also, are there other restaurants in Chicago serving equally creative food that I should consider?
