Intimate family only wedding, reception ideas?

Hi Everyone! We are having a small family only wedding and a reception dinner at a restaurant in a private room. My question is: how do we set up the dinner? Obviously there wont be a dance floor, or real need for anything like at a normal bigger reception, but how do we make it "fun" with so few people, so it's not just a dinner? Obviously we will have a little cake table, music playing and nice flowers and plates/silverware/candles on the table, maybe a little book or picture everyone can sign. Anyone have experience with this or can think of little things we can do, in addition to dinner? Thanks sooo much
