I've been to Vegas a lot, so that means I've been to plenty of restaurants there. I'd have to put Pampas probably in my top 3 places there.
We went with the Meat ridizio for 2 for our dinner. That's unlimited servings of different types of meats. When I saw unlimited... They had me sold. It also comes with a salad and side bar to add to your meal as you eat with a good amount of choices, but once they start coming around with the meats, you'll forget the side bar exist. My two favorite meats they serve are the sirloin and sausage. All of them were good though, ever the lamb which I don't even eat. They will make your plate full, so make sure you come with an empty stomach. The sangria is also a good choice to have as a drink.
The service was excellent. Our waiter stayed on top of everything and the servers of the meat will make sure to find you immediately when you're wanting more.
I was very impressed. I give 5 stars all across the board. You'll be plenty full and satisfied when leaving here. Pampas is definitely in the rotation to make a visit to every time I make a trip to Las Vegas.
