If you want to go to the theatre you should think about some things beforehand. First of all go to the box office and ask if they have seats for the day you want. Dont forget that the most expensive seats are in the front stalls or in the boxes, and the cheapest are in the gallery. The seats in the dress circle are not so expensive, but quite good, especially if they are in the first and second row. If you cant decide about your seats you can look at the map of the hall which usually is on the wall of the boxoffice and can be quite helpful.
