Ideas for Retreat Activity

I am thinking of having a retreat for my research teams during the lull period of our research. I thought it would be fun to just get together for some fun and relaxation and away from the office. Wondering what to do...
Escape room game?
Cooking class?
Art jamming session?
Soap making workshop?
Pottery class?
Terrarium workshop?
Cafe hopping?

I need a break. Need to recharge. Wondering where to go. Ideas?
