The IQ bar is a casual hangout, and not just for Einsteins. Located in one of the city's busiest nightlife districts, Zürich West, it attracts a mixed crowd usually already past their youngster years. The brickwork walls and the long bar make for a snug atmosphere. The ample collection of spirits on show makes clear immediately that they have a good list of cocktails and quite a selection of whiskeys and gins. If you’re getting peckish, they serve antipasti too.
