No, never been. I just looked whether there are any in the wider region but looks like only bigger cities have any, so an hour by car minimum.
I don't even have any LGS though, so a BGC would have positively surprised me.
I think I would like to visit a really nice one at some point just to try the experience. On the whole I prefer to play my own games - and to buy the games I prefer to play, needless to say - but going to a café with a nice small group and seeing what games they have could be neat.
