Lehka Hlava, which means “clear head,” has been a mainstay on the steadily growing vegetarian scene in Prague since 2005 and features an interior that can be only described as magical. One room is painted deep blue with stars. Another is purple with a lizard painted on the wall and has tabletops of colored glass. Along with freshly made juices, they serve lemonades, non-alcoholic cocktails, and samurai shots of Asian teas, as well as wine, beer, and cider. The menus change regularly and incorporate seasonal ingredients and produce.
