For my 18th I just went for a meal with family and best mate and then got a suprise go kart outing afterwards

They had hired out a track and there were about 9 of us blasting around it, top fun!
My 19th I had a birthday 'week'
Monday - went out for a meal with friends,
Tuesday - went to a posh club in Mayfair called Capisce,
Wednesday - decided to go all the way to Manchester, went out clubbing there with some mates at manchester uni
Thursday - came back to London and had a huge clubbing night at my favourite venue (bhangra night at Turnmills, Farringdon), was absolutely huge, last big night before everyone broke up for Christmas
Friday - went out clubbing and then a meal afterwards
Saturday - went out at home with my mates from home
Sunday (my actual birthday) - the whole family thing at home with lots of food and cake
For my 20th I want to hire out the Haagen Dazs Cafe in Leicester Sq and hold a private party in there.
