Where can I find real Italian Lemonade in the Milwaukee area

As the weather starts to heat up, I start jonesin' for some real Italian Lemonade. You know, the real stuff found on Taylor Street & elsewhere in Chicago. I've asked folks in Milwaukee if they know of any outlets, but I am usually met with either a blank stare, or they point out that Culver's has lemon ice in the summer. Brady Street in Milwaukee would be a logical location, but so far I haven't heard of anything.

Help!
