The second bar in the city where it all started. Just like its sister-bar, food and drink is served from a dedicated team of bar and kitchen staff. However, Castlegate brings something new to the table; The UnderDog, offering an alternative club-scene to the city, with great music and craft beer. Tucked away in the basement, The Underdog will be open to 2am and 3am at weekends.
