I went her with a bachelor party group.  We all stayed at the Monte Carlo and I suggested we walk over to Cosmo and check out this buffet.  We went on a Saturday.  I wasn't sure how it was going to be.  We were a group of about 10 and they sat us on a really cool long table.  Now my taste were fully function due a long night of drinking so everything was like heaven entering my dehydrated body.  They had a good mix.  The buffet wasn't amazing but then when are buffets really amazing?  We didn't pay the dinner price so it wasn't that bad.  I highly recommend checking Wicked Spoon out if you are staying in the area.  Cheers!
