GBG belongs to you
I don't love Air France, but I do love Göteborg and would move there in an instant if I could, so that's more than enough reason to endorse AF member Joel Karlsson's personal recommendation list for the city: http://www.thelineofbestfit.com/features/city-guides/joel-karlsson-air-france-102151
I'm not familiar with every place he recommends, but I wholeheartedly back Solrosen as one of the best, most friendly and affordable places we ate on our recent trip.
