Here in Chicago, there are plenty of well-known Irish establishments. They range from corporate-owned chains in the city to family-run enterprises in neighborhoods both downtown and the surrounding communities. Their rating on the authenticity scale covers the range from phony (neon shamrocks) to genuine (red-heads on both sides of the bar). Perhaps none truly embodies the true spirit of Ireland more than a relative newcomer, Peggy Kinnane’s Irish Restaurant and Pub in Arlington Heights. Operated by Owner and General Manager Derek Hanley, Peggy Kinnane’s, has become an absolute cornerstone in the revitalization of the downtown area in northwest suburban Arlington Heights.
