Review for Cypress Bayou Casino Review For Jimmy Buffett's Margaritaville at River Spirit Google User Feb 13 '18 at 1:31 We went to take advantage of the generous birthday gift of 2 free buffets and $10 free play. Out of all the local casinos I feel River Spirit does the best job of giving back at all levels. They make you feel valued and reward well. Always super clean, helpful and kind staff.
