I am going to be in Milwaukee in July for a conference and will be staying near the convention center. Typically, restaurants near convention centers are very "touristy" but I will not have time to start taking taxis to the surrounding areas. Can you give me some great restaurants and brewpubs within walking distance from the convention center area? I can walk up to 30 minutes. I will go to very expensive restaurants or "dives" as long is the food is Chowhound quality.
