Food was quite good, but service was not.
We ordered the "Caveman's Delight" (all-you-can-eat meat). Some of the meats were very good, some so-so, some no-so great. Overall, the food was satisfying and we enjoyed watching the trolls playing slots just beyond the comfy confines of the restaurant.
The service started out promising and the meat servers were more than generous with their offerings.
Unfortunately, the service began going down hill about midway through our meal and turned downright poor as we finishing. It was like our waiter had left for home in the middle of our meal. BTW, the service was not nearly as pathetic as OTTO (over at the Venetian), but could be much better.
I might try it again, but probably not.
Bottom line: If you've had a bunch of drinks during the day at The Mirage pool and don't feel like venturing far from the hotel, this may be a good choice (especially if you like meat, but are not a meat snob).
