On the opposite side of the river to Somerset House is the new rink on the London Aquarium roof terrace, open until Sun 4 Jan. As skating beneath the London Eye must be one of the most romantic things to do this Christmas, you'll need to book in advance through Ticketweb (www.ticketweb.co.uk). Bar Med, close to the London Eye and in the County Hall complex, is a place favoured by young-at-heart folk who want to get into the party spirit.
