Workmen are making changes at 688 Mt. Pleasant Rd., the long-vacant home of DeSantis Men’s Hair Salon and the space at 692 Mt. Pleasant between Meridian and Starbucks. Little is known of the tenants but the activity is welcome. Below is the street in 2011. DeSantis shared the corner with the much-remembered Lai Toh Heen and Sweet Gallery on the corner. Across the road Timothy’s was at Briton House.
