TREASURE ISLAND — The island will soon be home to a national restaurant-brewery chain.Owners of Sea Dog Pub and Brewery are planning to open their third location in Florida at the former site of Captain Kosmakos Bar & Grill, 9610 Gulf Blvd.The Maine-based company has a pub, brewery and restaurant in Orlando, along with four in Maine and one in New Hampshire."It's a great location" said Fred Forsley, owner of the Sea Dog chain. "We like Treasure Island and the whole Tampa Bay area. We believe there will be strong demand for our product here. It's a good location for our concept."The company, founded in 1993, was purchased by Forsley and his family 11 years ago. Sea Dog, which boasts that its beer is brewed in the traditional English style, also sells its products in retail outlets like Publix, Winn-Dixie and Target.No permits have been issued yet for the brewery, according to Paula Cohen, the city's community improvement director."We are in the process of doing the plans right now," Forfley said.The second floor of the two-story building will house a 6,000-square-foot restaurant that overlooks the Intracoastal Waterway. The restaurant will be open seven days a week serving lunch and dinner, he said.Forsley said he doesn't expect to make any major structural changes to the building but will reinstall the docks behind the restaurant and provide outside seating.The Treasure Island location will offer more seafood than the Clearwater site, he said, and additional types of beers.He said he expects it will open within six months and employ 60 to 90 people.The site was the former home of Captain Kosmakos, a popular waterfront restaurant and dance club, which closed several years ago and has been vacant since.Treasure Island officials are happy about the new business development."We welcome a business that's willing to take a chance on Treasure Island," Commissioner Ken Keys said."We are anxious to see some development in the south end of town that is compatible with the area and this sounds like it is," Mayor Robert Minning said.
