London Theatre early June

If there is a particular play/musical you have your heart set on seeing, it's best to purchase tickets in advance via a site like www.ticketmaster.co.uk. Otherwise you can wing-it and purchase tickets to lots of performances on the day either at the theater box-office, or the discount TKTS booth at Leicester Square.

I agree with Michael. As far as where to book, the website theatremonkey.com is a great resource for information on shows and where to buy tickets. For each show, they will tell you what agency runs the official box office and various other agencies that sell tickets. They also have info on fees, as well as seating charts. The tkts website that Michael mentioned has a link that shows what is available at the half price booth each day. If you take a look at it before your trip, you will get an idea of what you might buy at a discount in London versus what is only available full price. Some shows like Wicked or War Horse are almost never available at the Half Price booth. Others are easy to find.

As far as what is not to be missed: that depends on personal preference of course, but here are my thoughts about a few that made an impression on me. When I'm seeing a show in London I like to see something that seems very British to me (I'd save Jersey Boys for New York, for instance). I love musicals, so Billy Elliot was perfect for me. The talent in that show was astounding. For a non-musical, the iconic The Mousetrap was very enjoyable. A lot of people like Wicked and I thought the singing was fantastic, but for me it doesn't fall into the "not to be missed" category and doesn't fit my preference for "British".

Kathy If you fancy some Shakespeare the Globe has Henry V from 7th June. It should be a good production. It has Jamie Parker as Henry, and he was excellent in Henry IV recently. Even if you think of Shakespeare as stuffy the Globe is worth considering. It's a reconstruction of the original theatre and very atmospheric. Their productions are consistently good but stick to the original closely: no arty interpretations! http://www.shakespearesglobe.com/theatre/on-stage/henry-v Alan

I second the Old Globe option. Great fun and for me a London theatre experience not to be missed.
