RateBeer seems to suggest it's pretty average. It does better at Gray's reviews, but it's a much smaller sample size and there may be a correlation with the age group there. Also note that the last one says it was old and undrinkable.
And unless you know how old it is and how it's been treated, none of that means much. It could be the best beer in the world, but if it's been sitting out in the sun for the last 18 months... :icon_vomit: Then again, if the empty bottles are of any use to you, it might be worth the risk.
