For us we do the same as you pretty much, nice dinner, cake, and some gifts, sometimes no gifts..
For ayla she's had the one birthday, just close family came, we did the cake, presents and a meal and that was good enough for this time around..
I think in the future as she gets older I want to try themed birthdays..like the camelot miniture gold place we have, I would love to have a renaissance themed birthday sometime, and one year I'd love to have a Fair theme, since the county fair is so close and is during her birthday ..things like that I think would be really neat to do..
I just remember from growing up the birthdays I remembered the most were the themed ones, oh and the scavanger hunt birthdays were REALLY fun
