If you go to Krakow and miss Rynek Glowny, you’ve missed the heart of the city! The prices in Sukiennice are pretty much the same as in the rest of the city, so don’t be afraid to shop there. If you go in the evening, you’ll get to see breakdancers, fire-jugglers, accordion quintets (who seem to only know 3 different songs…), guitar soloists, and all kinds of other random entertainment. Don’t miss the “hidden” mall! It’s accessable via the stores to the right of St. Mary’s Church (when you’re looking at the church). Walk past Empik and the next few stores until you get to Benneton and the surrounding stores. If you go in them, you’ll find they each have a back exit (or a second floor) that leads you out to the common area of a mall. I lived in Krakow for 4 months and almost completely missed this.
