Overall, that restaurant had a 4.7 star review rating on Yelp.com, and most customers seemed to be very satisifed with the service, food, and atmosphere.
...but it only takes ONE bad review to bring down your business's reputation
There are potentially HUNDREDS of customers that read that one bad review, and then decided to go somewhere else (even though the review could have easily been a fake competitor review)
The truth is, customers give a lot of weight to what others are saying about your business. And over 94% of potential customers will read reviews about your product or service before even thinking of making a purchase from you...
To combat just one horrible review like that, It could take dozens of exceptional 5 star reviews on Yelp to convince a customer to purchase from you.
