Want to see a sneak peak of the Parkside on the Square condos? Head over to Main Street Market on your next lunch break. This month, the developers of Parkside opened a show kitchen and a design center on the mezzanine of the market building at 112 Main St. The space is a mock kitchen complete with the same quartz countertops, custom cabinets and appliances available in the $450,000-plus condominiums that will be finished next fall.
