Cafe Louvre makes anyone feel like an old movie star. It's one of those fantastic spaces that was once a social palace back in the days of the first Czech Republic, but was then acquired by the Communists and kept for good wholesome Soviet activities such as drinking tea. Now it's back in private hands, and is exactly what it should be: open to anyone who wants to come and feel classy.
The hot chocalate in Cafe Louvre is the best I have had anywhere; less a drink than a bar of the stuff, melted in a cup. It reminds me that chocolate really is a drug, superior to caffeine. The first time I drank it I couldn't stop laughing after the second cup, my whole being just satisfied.
The billiard room is a reminder of what the activity of billiards once was, before the movies made it the greasy violent swindler's lair that it is now, in the minds of many.
You could bring your grandmother here, or your hot date, and have a great time. One nice bonus is the pad of paper and mini-pencils that are always on the table.
