According to Wikipedia, in what appears to be a well researched (for a change) article, yes and no.
While lab grown meat exists (and was in fact first presented in 2013 at an experimental scale) it's not actually meat in the way that a steak is.
It's a replicated single type muscle cell it seems, so lacks the variety in materials found in actual meat. It's pretty much pure collagen and protein, no fat at all, for example.
Also, the cost is horrendous. Again according to Wikipedia it cost about $5300 per kilo in 2017 (last data they have about cost), hardly something to compete with the $25 or so per kilo of real steak (medium quality cuts), let alone with the less than $10 per kilo for mince meat, which is all that it's been used for in experiments to date.
IMO (and that's personal opinion) you're more likely to succeed in breeding lab cloned cattle and slaughtering those. Probably going to be a lot cheaper, and provide a better end product (and it's been done, at least with sheep). Whether you'd call that lab grown meat is up to you.
