I went to one of these about 9 years ago, and to be honest I had no idea they were still a thing. They were very talked about back then but I hadn't really heard of them again until now.
It was an enjoyable experience, and it was when I first moved to London for my first job so it felt very trendy and cosmopolitan and grown-up to me. Maybe I should look into it again...
I have enjoyed the supper-clubs of Buenos Aires in the past, partly because it was much cheaper and better food that the restaurants (from what I understood, it was very difficult to get a kitchen and/or liquor license) and partly because it was an interesting way to meet people. I think this is an international space that AirBnB is successfully filling with their experiences?
We do a private version of this with friends a few times a year, each household takes turns hosting a full dinner party, sometimes with a theme and sometimes not.
It's a good way to exercise one's hosting skills, keep in practice in the kitchen, and socialize.
Is there a website that anyone uses that focuses on the United States?
This website is beautifully designed and very readable. Good to see there are still websites that care about the users experience.
