Not sure if this exists in your area, but in Utah there are a few places that do "art night"; basically they supply canvas, paint, aprons and you get to go paint a picture and they supply wines and tapas from a few great local restaurants. It sounds like so much fun to me!
You could set up appointments to see a psychic and get coffee afterward. A few of my friends have done this for fun. Some of them "buy into it" and some do not, but either way it is different and fun.
You could get pedicures together, perhaps at a beauty college to save money.
Or you could even picnic- gourmet style. Look up a cool hike and pack some yummy food, don't forget to bring your camera.
