Spiz is a pub on the corner of the Rynek market square. It is a microbrewery serving the best beer in Wroclaw, perhaps even Poland. Plus you also get a free bread and smalec (dripping).
I found Wroclaw to be a very romantic city where you can always see couples wandering the streets. I always enjoyed meandering around the beautiful old town and relaxing in the park overlooking the cathedral.
Spiz is on the corner of the Rynek facing the flower market (Plac Solny).
