Review for Plainridge Park Casino Review For Silver Slipper Casino Google User Feb 23 '18 at 1:02 New outdoor pool with bar. Voted best buffet. 3 years in a row. Make sure you get in buffet line by 9pm. No exceptions. There's usually a huge 6'8 guard ensuring no one gets in line after 9. Not even 9:01 ?? View full site to comment or like
