It's best to do an activity. Go somewhere, let them do something (At two that would be play in specific way...gymnastics, tumbling, music, indoor swimming, etc.)
West Valley gymnastics does b-day parties. We've never ha nor been to one, but my daughter works out at the gym and loves the activities and has since a toddler.

We did a mommy and me swim lesson with a Nemo theme. It was a great time. We gave everyone a Nemo swim ring or kick board for a parting gift.
