Review for Dover Downs Hotel & Casino Review For Napa Valley Casino Google User Jan 5 '18 at 4:46 This place is nice cozy and friendly. The players are helpful and the people who work there are extremely nice. The dealers encourage you and help you win. I went for 3hrs with $60.00 and came out with $1900 by Playing blackjack. I love this place. View full site to comment or like
