Gaucho is definitely one of my go-to restaurants when I am looking for a homely and satisfying meal. The decor is rugged - in coherence with the name - but the ambiance is warm due to the friendly and attentive staff.
The variety of meats is what usually defines Brazilian BBQ, but every now and then I would actually forgo the rodizio and only eat from the salad bar, which is also an option on the menu.
The meat is juicy and flavourful and the salad bar offers fresh greens and my favourite black bean beef stew.
I believe the prices are also very reasonable for all-you-can-eat.
The only main criticism I would have is the lack of consistency in the quality of the meats and service. Although neither has ever actually been "bad", there is that occasional moment where a certain dish, or meat, and attentiveness of the staff would be slightly below its usual standard. For example, the parmesan beef could sometimes be overcooked, or the bean stew a little more diluted than usual, and a server could take too long to bring the cheque.
Nonetheless, my experiences at Gaucho on a whole have been great. I would definitely keep coming back!
