Seison Restaurant & Lounge can accommodate for private events and business functions. Being conveniently located within the Washington Inn Hotel, our additional conference rooms and banquet facilities can accommodate up to 150 people. The conference rooms can also be divided to provide a more intimate setting for smaller gatherings, which would also be perfect for small business meetings as well as birthday or cocktail parties.
