Well a facsimile is difined as an exact copy which is not what a vegan burger is. In my experience the best ones aren't trying to taste like meat and if you go in expecting one to taste like meat you're going to be disappointed before you even take the first bite. Thats like drinking coke when you thought it was milk.I'm pretty sure I have had good vegan patties and they are a facsimile of the real thing. That said, there a ton of good vegan meals. Attempted replications of beer aren't one IMHO.
