For the most one-of-a-kind fry anywhere, head for 
American Serbian Hall (53rd and Oklahoma, 414/545-6030, $10), recognized as the largest in the nation. On Friday night, this hall serves more than a ton of Icelandic-style or Serbian baked fish to more than 2,500 people (make that two tons on Good Friday).
The operation got so big that a drive-through has been added, which serves an additional 1,200 patrons. Unreal—watching cars backed up for miles while next to the complex waiting patrons (many chattering in Serbian) engage in fun-spirited bocce ball games.
This author loves the side dishes of beans and rice, ensaladas, and the Puerto Rican batter on the fish at the United Community Center’s Café el Sol (1028 S. 9th St., 414/384-3100, $9).
