Looking for some place new to try in Manchester, NH
I liked Gaucho's when I visited it a year or so ago. My experience is more or less the same as reported by "rcianci" (except that I haven't tried the churrascaria in Nashua yet).
Other suggestions: Indian Palace on S. Willow Street, La Carreta a bit west of exit 9 off I-93 for Mexican
Can't respond about Taste of Europe because I've never eaten there, but I used to eat at Gauchos a couple of times a month.
On the plus side, I think the meat at Gauchos is very, very good. It's the best meat I've had in any churrascaria so far (and I've eaten in quite a few.) I like that they bring you the best cuts first instead of trying to fill you up on the cheap stuff. The salmon on the cart with the caper sauce is great as are the fried bananas, black beans and rice, and the chimichurri sauce.
The yucca fries are tasteless, but then all yucca fries are tasteless to me.
On the down side, the baby new potatoes are always way overcooked. The salads are just boring average salad bar fare with little that screams "Brazil". The cheese bread is doughy and tough, and the desserts (Bindi frozen and thawed) are the weakest part of the meal. Another negative is that they no longer sell wine by the glass.
These days I get my churrasco fix at Sabor Brasil in Nashua because these days I'm more interested in authentic Brazilian salads, sides, and desserts, but if good freshly grilled meat is your focus, I think you'll like Gauchos just fine.
