A very good buffet at the M hotel.
High lights: fresh crab, gelatto, huge variety, unlimited booze, coffee bar, very new and clean.
The prime rib was kind dry and not very flavorful, overall it was good but some things were ok/bad
I hear it's super busy on the weekends especially at night, we went on a sunday lunch and we got in very quickly
Also, it's quite a ways off the strip beaten path, so not sure it's worth driving the 15 minutes to get there if you are at the strip. Might be a good place to hit going home or first arriving though.
