I love churrasco, and especially a good churrasco. But, the two problems with rodizio is that a good one is generally expensive and you end up eating too much. Montana Grill has surprised me by solving these two problems. Now they have this (executivo) lunch menus, that are accessible and you get to eat a great meat without the risk of eating too much. It comes with a salad entrance, the main dish with some options of sides like potatoes and rice, and ends with a dessert like a pineapple that helps you digest. It is a great meal, for a good value.
The one warning is that even though they have many waiters, each dish takes a long long time to come. I had to ask for my dessert three times, to different waiters, and still took like 15 minutes to come, so, make sure you have time to spare. Still, it is definitely nice to have this option at a traditional churrasco place. Of course, they still have that rodizio option.
