One of the best places to visit in London. Quick tips:
1. buy the ticket in advance over the internet
2. definitely visit with Yeoman guided tour (every 15 min, no extra fee) - this is a must as it makes it more fun and memorable
3. go early in the morning to avoid the crowd, it gets crazy in the afternoon
4. jewelry rooms are interesting but not sure if it worths 1-2 hour of wait on the line
