Café Savoy
One of the best of Prague's traditional turn-of-the-century-style grand cafés, the Savoy is popular day and night for its brunches, coffees, Czech classics, and pastries. In particular, try the větrník, a Czech classic made of choux pastry with cream and caramel. It's far more authentic than the touristy trdelník (a type of rolled, spit cake) available everywhere, although if you need that sugar hit to get up the hill to the castle, no judgment. It's also an opulent but still traditional spot for a beer in the evening—or heck, go all out and get some sekt (Czech sparkling wine).
