The Daryl Powers Salon and Portabella’s Market in Berkman Plaza are open to the public, but because there is no sign outside, foot traffic has been limited. But that’s starting to change. “Business is growing everyday,” said Greg Larson, store manager and chef at Portabella’s Market. “We get business from the courthouse, police station and a lot of the tenants use us for lunch and dinner. ” The salon offers full spa services, including massage, facial, pedicure, manicure and shampoo and cut and style.
