I never stepped into their shop yet upon checking Borough Wines (the site) I imagine it to be the modern version of a Cave a Vins not that they pour wine by the glass besides selling bottles as far as I know.
They take the pain out of wine buying as their poster above shows.
Mostly French choices, Italy, Austria and New Zealand round up the selection.
The shop is located in Borough Market, London.
The market is opened
Thursdays: 11am - 5pm
Fridays: 12pm - 6pm
Saturdays: 8am - 5pm
With extended hours for the Holidays
