Yes, its pretty interesting if you like The Beatles. The owner, Gibson Kemp replaced Ringo Starr when he left Rory Storm and the Hurricanes to join The Beatles. Also Astrid Kerscherr, the photographer who is portrayed in the film
Backbeat is a regular customer. I think some of her early photos of the band are on the walls in there.
They also carry a nice selection of English bottled beers.
