Whether you are rushing for your train, running late for a meeting or so absorbed by the sights of Prague that you don't have time to have a sit down meal, do not despair. Dotted all over the city you will find take outs, from just a coffee to sandwiches or from pizzas to full vegetarian meals.
If you are an Indian food lover, pop into Dhaba Beas, 100% vegetarian, but also much appreciated by carnivores. If you haven't tasted bratwurst with a big dollop of mustard, washed down with a large mug of Czech beer you haven't been to Prague. They are best eaten with a heap of sauerkraut while leaning on one of the stand-up tables on Wenceslas Square. More stylish are chlebicky, open-faced sandwiches, Jan Paukert at Narodni Street is one of the best delis to get them from.
