What are your recommendations for a very small (like 5 women) baby shower/sprinkle?

I was thinking tea party--do we go out somewhere, or invite everyone over?

Or have everyone over, then go to a salon for a pedicure?

What kind of mama-centric baby showers have you been to and what do you recommend?

PS I'm hosting, and I only know the mama, the others are her friends that I don't know yet.
