Ordinary people review local establishments in a certain radius and often their reviews are pretty good. Disregard the two top reviews and make an assessment. I have no interest in 'Yelp" whatsoever but have used it to find directions to a pre-selected place and found the reviews in retrospect pretty good. You need a smart phone or internet service.
BTW I visit Belfast usually every year and its a great place. I have a few friends who live there.
Have fun
