The award winning Galeria Lodzka has been open since 2002. It is close by to Piotrkowska Street and the mall is spread out over 3 floors. Besides the usual shops that you find in these shopping centres, the main reason I visited a number of times was the food court with a number of outlets to obtain a variety of different types of meals. Other reasons were the large supermarket to obtain snacks and drinks, a coffee shop and access to the internet
Manufaktura has the widest selection of shops, you can find upmarket ones such as Hugo Boss, Escada Sport, Lacoste but also the regular ones such as Zara, H&M, C&A. You can also find some other shops very local and very different such as the cigar shop, a typical bakery.
What to buy: You can all you need.
What to pay: Depends on you wallet
What to buy:
Silver is cheap in Lodz and in Poland in general. Go to the markeds in the centre and you'll probably by them all (like I almost did)
What to pay: depends on how much you're willing to buy
