How it compares locally

Across the 96 clinics we list under Bariatric Surgery in İstanbul, the average rating is 4.9. This one is at 4.7, which is the middle of that field rather than either end of it. It is less documented than most, though — 3 reviews, where the local average is 99. A rating on fewer visits is a less settled one.
