Review for Mystic Lake Casino Hotel Review For Grand Sierra Resort and Casino (GSR) Google User Apr 14 '18 at 18:17 I like the fact they have a second-run movie theater and a Round Table Pizza in the basement. I also like the different concerts and events they book (probably the best in town). But the couple times we stayed in the rooms or visited someone, we have been disappointed. Extremely sloppy housekeeping. As if they just added a couple towels and left. So not impressed with the hotel aspect at all. Much better rooms elsewhere. But the rest is nice.
