Please Note: Just because a shop is listed as having a 24 hour alcohol licence doesn't necessarily mean that the shop is open 24 hours a day, 7 days a week. It's also worth noting that large 24 hour supermarkets (Asda, Sainsbury's and Tesco) are not open all night on Saturday, Sunday and bank holidays (due to Sunday trading laws in England and Wales).
