Review for Diamonds Casino Review For Diamonds Casino Google User Jun 22 '16 at 0:36 We were so looking forward to visiting Teno. This place was such a disappointment! The best thing I can say about it is that the beds were comfortable! The casino was full of the filthiest crack head looking people , we were afraid to touch anything! We just went to bed and left first thing in the morning. Would not recommend this hotel/casino to my worst enemy! View full site to comment or like
