It's not all that unusual for a restaurant to pick up and move. North Star American Bistro migrated to a new space across Oakland Avenue in Shorewood a year and a half ago. Two venerable Milwaukee eateries, the Boulevard Inn and Chip & Py's, made cross-town moves before eventually closing. But a 70-mile relocation is definitely out of the ordinary. That is what Chris and Jennifer Giaimo have done with their Bellafini's Trattoria.
