Review for Oyster Bay Casino Review For Oyster Bay Casino Google User May 31 '18 at 7:02 Attended a conference in the Marquee. It is a large auditorium with good acoustics and visibility throughout. The food court offers overpriced eating options and most of the foot traffic though the building requires going through or near the casino. The casino is large and if you're loitering then you can expect scrutiny from an army of security guards. The casino itself has no visibility to outside so you cannot tell what time of day it is. The facility also houses some high end shops and a hotel as well as residences. View full site to comment or like
