Hacienda Mexicana is one of ten or so Mexican restaurants throughout the Czech Republic.
This restaurant seems to have designed itself around a very extreme notion of what "authentic" mexican haciendas must look like. While not a top choice for quiet, romantic dinners, it's a on the other hand a fantastic place for a party. All you need is a cocktail and a look around the festive interior and the party has begun. It's a rather pricy establishment, but the food is good. There is another Hacienda at Bilkova 2, with the same scenario.
