As a vegetarian, I'd eat it, but hold off for a while atleast to look for potential health consequences. I'm not too worried about nutritional imbalance because I don't think this will ever be my primary source of nutrition.
As someone who gave up non-veg food about 15 years back, I'd welcome lab-meat since it avoids killing animals. However, whether we would adopt it ourselves seems to be irrelevant. I, for one, would not like to cultivate the taste for meat again. As an animal lover, I'd certainly not like to see menu items like "Synthetic dog meat, tastes just like puppies". Going to the extreme, replace dog and puppies with human and babies. I'll stick to veggies, thanks.
