Most reviews posted for his restaurant are either 4 or 5 stars, with the majority of lower reviews referencing the other restaurant either by name, menu items, or decor. I'm not sure if the issue is one of UI design, mobile app, or poor search handling - although I heavily suspect search is the culprit.
Unfortunately there doesn't seem to be a way to address these mis-posted reviews, that I've seen. I would love to hear any suggestions that would help though.
