Lanzarote and Ibiza in "Bars of the World"

Recently, Lonely Planet in conjunction with Singha Beer, have brought out a guide to the world's best bars.  Included are:
La Cueva in Nazaret, Teguise, Lanzarote, Canary Islands  ... Off the Beaten Track
"Surely the most magical nightspot ever imagined, this surreal bar is built into volcanic cliffs with exposed rock walls.  There are tunnels, stairs, ladders and stepping stones across turquoise pools to connect the various bar areas.  Sip some Canarian rum and dance along to the tunes coming out of the caves above you."
Mari Pins in San Antonio Bay, Ibiza, Balearic Islands ... Pubs/Clubs
"The top DJs at Mari Pins really know what to play to get the party into full swing.  Fun themed nights and fun prizes [an evening's free drinks, a free jet ski ride], 80 different shots, lotsa lagers and an extensive cocktail list, coupled with a bar terrace and a snooker table, set you up for a great night".
