Searcys Champagne Bar, N1

At 300 feet in length, this is Europe's longest champagne bar. Banquette seating along a glass wall, you sit next to an awaiting Eurostar. Can be a bit noisy, but sitting beneath the masterful William Barlow roof spans is quite awe-inspiring. Champagne only here and including service, the cheapest bottle is £60. Something for a special occasion only or the very well heeled.
