Tesco

The Tesco brand of hypermarkets is well-known from Britain to Poland and beyond, so it's no wonder Prague has its very own, right in the middle of town. Whether you need to go on a large grocery trip, buy a tent for a last-minute camping trip, get some cheap clothing or even some Becherovka at below market prices, Tesco is the place. Best of all, the store is open until 10 pm on weekdays (8 or 9 on weekend).
