I've been to a few Brazilian Steak Houses in my day...and this was by far the worst. Sorry guys....I wasn't impressed.
Other Brazilian steak houses have an AMAZING salad bar. This place doesn't even have one. You have the option of getting the all-you-can-eat meat or a regular meal (for about the same price). Get get the same sides no matter which one you choose (it's a lot of food). We didn't go with the all-you-can-eat surprisingly...because it didn't look that good from what we saw. And we didn't see much. Usually the "meat guys" are running around constantly with something new. I maybe saw 3 guys coming around the entire time we were there. I don't think you would get your money's worth.
I decided to get a steak instead. It was not the best steak I've ever had. It was pretty fatty. The drinks are very good - I will give them that. Their service is also lacking. Our waitress was not very friendly or helpful, and she barely came to our table. We had to flag her down quite a few times.
I wouldn't come back here again. There are plenty of other place to dine within the Mirage and Vegas.
