That real estate 'ad page' isn't dissing the restaurant, but is touting it as one worth visiting (by those million-dollar property owners).
The review site itself is (only) Yelp and there have only been 13 reviews so far. Such a small number of reviews (=small sampling size) makes it hard to trust anything other than a mid-range score.
The Google reviews are far more positive and plentiful (92 mostly 4-5 star).
