Fénix is a fairly sizable shopping center in Prague 9 right near the Vysočanská metro stop. There's…read morea full food court with a range of dining options (Chinese, Italian, French...) as well as three floors of various goods. There's a post office and a grocery store and a paper shop, among others.
Prices are generally reasonable but it depends on the store. You can also find free bathrooms on the ground floor, which I for one really appreciate.
If you have the time and money, you can find plenty of quality items in this mall -- located about a 20-minute metro ride from the city center. I'd recommend.
