DH I did a surprise party for him had about 60 people and I hired out a function room at a restaurant and we had finger food and kareoke. Everyone paid own drinks. Was a great night!!

My 30th I had a dinner with about 16 friends (some were partners) and we had a semi set menu (eg was 5 choices of main and 4 of desert) and everyone paid own way. Was so nice to have my closest friends all together!! DS1 was 8 months old at the time.
