Review for Diamond Mountain Casino and Hotel Review For Lava Rock Grill Google User May 22 '18 at 4:42 Super comfortable bed, clean, restaurant near bar is really good. Has an indoor pool and hot tub, and is cheaper then red lion and super 8. No funky smells or anything in the rooms or hallways. Has a safe and kuerig in the room with complementary coffee.
