I you are looking for hearlhy groceries, such as superfoods, bio, raw, gluten free, veggie etc… This place is one of your few options in Prague as there are still not enough stores where you can buy these. They offer a nice variety of products, accept bank cards, are able to help you qith your choice… But in general most if the stuff is overpriced, for a grocery shopping I rather recommend Countrylife that is in Karlin next door to Sklizeno. A big plus from me in Sklizeno they have for the variety of fresh made cakes, cookies and sweets they offer in glutenfree/healthy etc variations.
