De Groote Griet (named after the canon that the inhabitants of the city used in 1972) is a sports bar. For anything from soccer to American football, ice hockey and any other sport you can think of, this is the place to be.
The fact that it’s a bar is nice too, as it makes it easier to have a drink while enjoying the match.
In short, for sports fans it’s a great venue at the Grote Markt in Groningen. And if you’ve had enough of soccer for a while, just walk over to one of the many other bars on the square.
