"UPSIDE is approved for sale in the US! Here’s what you need to know.

[...]
We’re thrilled to share that our cultivated chicken will soon be available to the public for the first time at San Francisco’s Bar Crenn, prepared by 3-Michelin Star chef Dominique Crenn. Chef Crenn is a friend and partner of UPSIDE’s and a long-time champion of sustainable food systems. Chef Crenn has developed an exquisite signature dish featuring UPSIDE cultivated chicken that will be available soon." 
That was posted in June, so it's not clear to me what they meant by "soon".

This resolves according to my own judgment, pedantry, and whims.

I won't count it if you can't get the cultivated meat without a reservation. I won't count it if I think it won't be available indefinitely, like if it's just a special promotion for only one weekend or something. It does not have to be Bar Crenn. If it is being served in an obscure, remote restaurant in a way that makes the product or service ambiguous, then I will resolve as ambiguous. Those are the only special conditions I could think of, but I will plan to revisit this market in a week to see if I think I should add any other major caveats.
