The Impossible burger is not cultured meat, it’s a plant-based product. OP is referring to this https://www.theguardian.com/environment/2020/dec/02/no-kill-...

Ah I misread his wording. I thought he was just asking for someone's opinion on restaurants that had served any meat alternative product, not specifically lab grown meat.

Impossible burger is still created from plants. "Clean" or lab grown meat isn't commercially available anywhere, it only exists is some labs AFAIK. It's sadly very expensive to make today.

There are a few startups working on this, Mosa meat and meatable are some examples.

That's not cultured meat. It's plant-protein based.
