The Dolphin is a pleasant traditional pub in a very nice location with a good view of Whitby Harbour and the pier. Alas, compared to some other Whtby pubs, most notably The Little Angel (which is five to seven minute walk away), the beer selection is very disappointing if you don't want to settle for the usual Greene King ales. When I dropped in during a short pub crawl of Whitby harbour, there were no other real ales of interest available, so I chose just 1/2 pint of Abbot Ale, which is one of Greene King's signature beers and a solid choice as a best bitter. I quickly left for other, more interesting pubs.
As a family pub for a solid if unexceptional lunch or dinner it will do.
