I've been to Bolero twice and as a picky meat eater, I only had to try the full skewer selection/Rodizio once. The second time I just had the Teaser Platter, being the Fresco Bar, Hot Bar with a choice of two meats. I nearly fell off of my chair when the two meat portions (I chose chicken legs and Linguica, my favorite) arrived. It is an insane amount of meat and I had leftovers for days. I had to share it because I'm sure I would have had the meat sweats and been turned off. There are some pretty good Hot Bar dishes but the Fresco bar is just okay. The vegetable skewer is good too.
I do think it's a cool experience that everyone should try once, but I'd only go back if I was invited by someone. If you are a hardcore meat eater, you likely would give Bolero more stars.
