Kaffee De Groot is one of those multifunctional hidden gems that ticks many boxes. It's located in a photogenic building near one of Eindhoven's most popular squares and its giant terrace is one of the better people-watching spots in the city. While it's not a proper restaurant, small snacks can be had and a number of tasty brews are also on offer. Locals also flock to this place for live music concerts.
