Anna Metzger and Kristin Pasquino sit in Wunderbar, the five-month-old coffee shop in Harmony, on an early Friday evening. Metzger has lived for 47 years in this small town just half an hour’s drive from Pittsburgh in Butler County, but it took Pasquino’s urging to finally draw her down here to the Center of Harmony. The Center, housing six businesses and an event space, opened in November in the town’s 140-year-old Oddfellows hall and opera house. The place had seen its share of manufacturers and other food establishments through the years, until nearby Connoquenessing Creek flooded it out of business during Hurricane Ivan in 2004.
