Versal and Black Sea both appear to be Russian restaurants on Fairfax between Beverly and Melrose. They both have dark windows, and in three years of living in the neighborhood, I can't recall ever seeing anybody entering or leaving either one of them. Versal is on the west side of the street, a few doors up from Chameau. They've recently opened a "Eastern European Deli" next door. Black Sea is on the east side of the street close to Fairfax High School.
They both always appear to be closed, but they both have up-to-date health inspections listed on lapublichealth.org, so they must still be in business and serve food of some kind.
What are they? Private clubs? Banquet halls? And, most importantly, is their food any good?
