When you decide to visit London keep in mind checking ahead of time two great theaters websites to see if you can still find some attraction available for your days and nights in town. British are really thorough with reservations and being ahead of time to get tickets is very important.
The Old Vic first opened its doors in 1818 and always has amazing plays on. I recently saw Electra, Frank McGuinness adaptation for the Sophocles' tragedy, there and the ambience is very intimate and enchanting.
The Royal Albert Hall has been around since 1871, conceived by Prince Albert to promote appreciation for the nation's art. It is worth a visit for the impressive historic building and for the many concerts, shows and ballets that are always on here.
