Birthday Celebration at a London Pub?

l am gonna be twenty five on June eleventh and l want to celebrate in London this year. With all my birthdays l have never had any proper birthday nights out.

I don't fancy going to a restaurant because l would expect everyone to pay their own way and l can't pay for them. l would want to celebrate in a bar or pub on the tenth with friends from college and school. Does anyone know any good bars or clubs in London? Then another problem is l want to celebrate with my cousins in a club in London on the twelfth. I could use some help there also.
