My husband I did a Thai cooking classes recently. It was lots of fun, and we've actually started cooking together on weekends, which we haven't done since we became parents.
Let me know if you're interested. It costs $500/each and you need at least 4 people to start a class. Maybe you can get another couple to join you?
The teacher is fantastic. She's a chef and her mother owned a restaurant/caterer while growing up.
