Review for Diamond Mountain Casino and Hotel Review For Lava Rock Grill Google User Dec 19 '17 at 17:27 Nice room and nice in-door heated pool great for any time of the season. Hotel provided us with food vouchers to the restaurant. The food there was great! The food service should have been faster however, perhaps more staff during the evening. We had a bit of a wait time just to take our orders. View full site to comment or like
