I like this place for the experience but it's been hit or miss. I've been to Fogo many times, three times in the past two months. One of those times is was fantastic, one was average and one was a disaster.
Good food if you can get it. Avoid this place on a weekend when it's packed. I saw one person serving meat in the entire restaurant on several occasions one Saturday night. They seem to care only about serving large parties and probably selling drinks more than anything. Then when someone asks what meat I would like to try, they don't come back. I brought two friends for the experience and left embarrassed.
On a good night everything is wonderful!
Salad bar is pretty incredible. Huge selection of fresh veggies, salads, meats, cheese, etc. I'm tempted to just get the salad bar if I go back.
Bottom line, if you haven't been there you should go. Like I said, maybe try it on a weekday when you get better service. It's a fun experience and be sure to come hungry!
Enjoy!
