It depends on what you like. I remember my 25th birthday, it was a disaster, considering I din't ask for too much. I wanted to go to a cool club that had opened in my city with all my friends after dinner with my then boyfriend at a nice place.
But the ex was so oblivious... he just took me to a place that we would have gone either way any other day, didn't get me a cake or balloons, my friend's car got screwed up (the one with a car that was picking up 3 of my other friends) and my other friend's mom was hospitalized. In total it was 6 people (including me and my boring ex) in the most boring birthday party. I broke up with him after that, I couldn't deal with that.
Anyhow, that was my taste by then... so your may be entirely different depending on your personality.
