First, let's drop some names from the Urban Life section (this is the useful part): Stucki Bruderholz, Le Lertzbach (just across the burn, btw), NT/Areal, Acqua, Fumare Non Fumare, Chez Donati, Grenzwert, Campari Bar, Coumou (already closed), Das Schiff, Bar Rouge, Johann, Nuovo Bar, Eo ipso, Noohn. I'll admit straight away that about a third of the names I have yet to try, so coming from a native, that is already a compliment. The other places are definitely top rated in town.
The Wallpaper City Guide is quite a useful small (very!) companion catering to the urban chic city traveller who doesn't care much for the jetsam that traditional guides provide. In that, it is also handy for the native who might discover a new gem or two in the place she calls home.
