We were staying at the Courtyard by Marriott Washington Convention Centre hotel and meeting friends that live in DC. It was a freezing cold night so we were delighted when they suggested we eat at GB's - English pub style with a decent selection of beers and accessible straight from the hotel. Service was initially a little frosty, but our server soon warmed to our British sense of humour. Food quality and quantity were very good and the atmosphere was pleasant. Good value for money.
