"El perro cocinó un plato muy bueno."
Translation:The dog cooked a very good dish.
Interestingly, just changing bueno to bien seems to change the meaning to The dog cooked a dish very well.
it does, but that would be because one is an adjective and the other is an adverb, also you would need to change the punctuation
I agree with 21JoshuaJohnson: How? Google "The dog cooked a dish very well english to spanish" and you'll get the original sentence with bien replacing bueno, only.
