What are some fun birthday activities for a 33 year old?

Next month my three best friends are coming to town to spend my birthday week with me. I'm turning 33, so not a milestone birthday, but we haven't seen each other in nearly 5 years and our schedules have finally aligned for us to see each other! I'm so excited because I've missed them! We live on opposite ends of the country, and one lives out of the country, so I want to make their travel worth their time.

They will be in town for the entire week (it's the week of September 21). I want to do more than just the typical going to a restaurant thing. The only thing I've seen that I truly want to do is go to a place called Case Chocolates and do their tasting experience. Other than that I'm drawing a blank. We aren't club people. The most we'd likely do is maybe go to a bar one night, but that's it. I also have planned one day for us to do nothing but watch tv and talk (it's a traditional thing we do when we all reconnect).

Any fun experiences that we should do?
