Going to the Shopping Malls:
Copenhagen has two popular, large shopping malls.
One of them is Fisketorvet, situated beside the harbor, on the outskirts of the city center. Here are shops and great restaurants in abundance, and a movie theater offers entertainment as well.
Situated in the Copenhagen area called Frederiksberg is the Frederiksberg Centret Shopping Mall. It is approximately 10 minutes by bus from the City Hall Square. Frederiksberg Centret is a fun, modern mall with a variety of shops with clothes, shoes and accessories.
Shopping for Designer Fashion:
Strøget & Købmagergade are the longest shopping streets in Copenhagen (Stroget even is Europe's longest!). International fashion from Prada, Louis Vuitton, Cerutti, Mulberry, Chanel, Boss, and many others are found at the Kgs. Nytorv end of the Strøget.
For lower prices, head further down to clothing stores like H&M. On the side of Amagertorv lies Købmagergade, featuring small independent shops with clothing and eyewear.
Flea Markets in Copenhagen:
In Denmark, there is definitely a passion for a nice stroll around local flea markets. No matter if you're driving through a large city or walking through a small town, you are unlikely to miss one on summer weekends. In Copenhagen, there are three major players. Frederiksberg and Israels Plads flea markets offer great value. Gammel Strand, however, is unique with its canalside setting and outdoor coffee shops. The flea market season in Denmark starts in late May and ends in early October.
