Cloud 9 Sky Bar
This chic, lounge-style bar, situated on the rooftop of the Hilton Prague hotel, offers glorious views of the Czech capital (including parts you don't usually see). There's an extensive menu of innovative cocktails, as well as some beautifully presented snack food; try the chicken lollipops and prawn popcorn. The music can be very loud in the evening so it's not the place to come for a quiet conversation.
