We can go see ballet whilst eating crisps and drinking beer.

Over the weekend, the Royal Ballet did several performance of Romeo and Juliet at the o2 Arena in East London, as a way to make the ballet more accessible to everyone.

we can go to hardwick hall.

This amazing house was built by Bess of Hardwick, the second most powerful woman in Elizabethan England after the Queen. It also used an uncommon amount of glass for the time, hence the rhyme: Hardwick Hall, more window than wall. It was also featured on the BBC show Britain's Best Buildings and has one of Europe's finest collections of tapestries/textiles.
