Now this is funny:
Check out the Yelp reviews prior to and after the zero star review...
Looks like a bunch of young "influencers" jumped on to belatedly recall and post about a less than stellar experience...Granted, there were some clunker reviews in the past too... Overall 4 star avereage out of 5600 reviews?
