Glück is a genius combination of café and kids’ playroom. Parents pay for each child’s entry so that the kids, supervised by café staff, can amuse themselves with a full array of toys and games while the parents relax, have coffee, and wedge in some adult conversation. Tables come with electrical outlets so harried moms and dads can plug in and catch up with everything they should have done two days earlier. The menu features coffees and infusions, sandwiches, and pastries, all done nicely. Private babysitting is available at extra cost.
