Bachelorette activities in Hanoi

Xin chào các bạn,

I‘m a Viet Kiều and my fiancée and I are getting married in Hà Nội this October. I would like to plan some sort of „bachelorette“ day for my girlfriends and myself. I don’t want my friends to plan anything as they’re already coming all the way to Vietnam to celebrate our wedding.

I’m looking for a fun and/or relaxing activity that lasts for about 1-3 hours in the afternoon, so that we can grab dinner afterwards and maybe go to some nice bars (maybe the speakeasy-vibe kind of bars?). We’re about 10 people in total.

My ideas: some sort of workshop (jewelry, perfume, pottery, cooking, etc) or visiting a spa (but should be suitable for a group of 10).

Do you have any other ideas/recommendations for activities, workshops and/or bars? I’d be very grateful :)
