It's a Brasilian
churrascaria. The meat isn't actually from Brasil.
Disclaimer - My company is designing their website (so I may be biased).
I've been to Brasil and eaten in true churrascaria's so comparing Bolero to those it is a good approximation. The meats and styles are much the same. Only difference is in Brasil the salad bar is giant and as soon as you flip your sign to green the servers are all over you to the point you need to flip your sign (or remote as Bolero is calling it) to red.
I've had discussions with their management about their desire to recreate the "server mob" feel I experienced in Brasil and they are working towards that. Not an easy thing given the Calgary job market whereas in Brasil you could have a ton of staff on shift without problem. When I was there the servers came out steadily and we never really felt like we were waiting - except for pineapple.
I think it's a good dining experience, and am extremely happy Calgary has this option.
