... is the place where I live.

Good food can be bought on the Vismarkt market (Tuesday, Friday and Saturday), and in Le Souk or Ariola (both in the Folkingestraat).

If you don't feel like cooking, there's a range of nice restaurants: Uit de Buurt is the best, and literally (and metaphorically) ‘far out’. Vive la vie in the Oosterstraat (closer) is also good.

Then there is Mechoui (Moroccan), Cho Fah, Jasmine (Thai). Pizzeria Gabbiano (formerly called Eetcafé Michel which closed in 2020) has the best pizza in town. Wadapartja (Zuiderdiep and also Westerhaven) has terrific food in a cosy informal setting. For the best croissants in town, I used go to Super de Boer (now a Coop) at the Paterswoldseweg (opposite the Niemeyer tobacco factory). Really! (Then again, Gea disagrees.… ;-)

De Sigaar and Het Pomphuis (Hooge der A) have a nice terrace along the A, sunny during the afternoon.

For live music, go to Vera. There used to be nice parties/gigs at "de Silo", behind central station. Groningen is lacking good parties these days (Syntax Error - who organised great electronic music gigs - as well as Holodeck/ClubPlus - that used to organise bimonthly dance nights - have quit... sadly). Some of my friends startes Club Bavarois, a radio show to watch (not to listen to), "airing" at the Grande Theatre in the centre of Groningen on saturday evenings (irregular). The old sugar factory (Suikerunie terrein) east of the city has become a nice informal hotspot of creative people, and has some bars and venues too!

Each year, just before the second weekend of January, Groningen hosts Eurosonic. This two day European music festival (and seminar) features new and upcoming European bands, playing in major venues as well as small pubs scattered through the centre of town. Beware: the last few editions tickets sold out within a few hours. Presale starts early November.

Moreover, Noorderzon is organised in the Noorderplantsoen every year late in August This large yet cosy theatre festival in a park lasts for one and half week and covers acts ranging from street theatre to international dance (as in ballet ;-).

This gives you an idea where we go...

I am not a great fan of Dutch literature (Slauerhoff is one exception, See also). I do love Latin-American literature though: Julio Cortázar is my favourite, and also the inevitable Gabriel García Márquez.

Other stuff

I enjoy British comedy, like Blackadder, and Monty Python Flying Circus.

I like iceskating, playing tabletennis and billiards. More than ten years ago I took up karate, the Okinawan Goju Ryu style to be precise, at the lovely dojo Het Spoor of Chris de Jongh sensei. I still haven't reached the first dan.…


In the course of the years I wrote some small tools, and I did some Atari Falcon programming (but that was a looooong time ago).

I love Python.
