If you’re talking about
http://www.theshipinabottle.co.uk
are you sure it’s the same place?
Rather unhelpfully there doesn’t seem to be an address given and the phone number is a mobile so that doesn’t help. However the location map in the Contact section is centred on Wellingborough, which is nowhere near Liverpool. Also on the website is mention that the place used to be a gastropub and that it has a games room with pool, table tennis & darts. Frankly, I don’t see how there would be room for any of that in the old bottle shop premises.
