Pros: big patty, fresh, someone speaks English Cons: Disappointing, over-salted, soggy…read more Let me explain. This place has a reputation of being the best burger in Brazil because of some associated chef's legacy and three different meats put into their signature patty. It didn't feel that gourmet to me, just a typical pub burger. I made my own burger medium with the signature patty, lettuce, tomato, Brazilian cheese, and pickles on a sweet potato bun. As well as fries. The burger came to me wrapped up in a bag with my fries; I was perplexed to find the bun already soggy, as I ate it in the restaurant a minute after they made it. The toppings were fine, nothing special except the cheese, but the burger was definitely rare and very over-seasoned. I'm not sure if this is a Brazilian thing, the under-doneness, but eating raw meat in a country you aren't from isn't the best idea. However, the fries were done properly-hard to mess those up. The tables had a couple of sauces; a ketchup that tasted like bbq sauce and a sweet chili sauce. Very random. Would I come here again? Most likely not. The price of the burger is a bit high and it just wasn't that memorable.

We heard this was The burger place to go for quality burgers in Rio, but we found that was not…read moretrue. It was a bit pricier than most other places we ate during our stay and the burger was very underwhelming. It was a bit bland and the cheese and condiments they had didn't do much to help with the flavor. Not a place to go if you're on a budget, there are better places to dine while in Rio.

Super filling and yummy burger near Ipanema beach! I got the B de Bem-bolado and was pleasantly…read moresurprised with the size, the fries can be ordered on the side if you'd like any. The burger will be given wrapped in wax paper to reduce napkin use (i was told it's a common thing in Brazil). Sauces are available on the side, ketchup, mayo, mustard, and bbq! The space itself looks tiny upon entrance but they have their sitting in the back and also on a second floor I didn't see. Would definitely recommend if you're in the area.

Awful service. As…read morean American you can sit in their empty restaurant for 15 minutes and nobody will serve you or take your order. This from a burger place that charges 2-3x what a regular burger place does. So I walked out. They obviously don't need my business. Bye.

Far away from being the best burger in Rio. The burger is extremely greasy and the aioli sauce is…read morenot so consistent, what combined with the grease, makes the bread really wet. I miss some flavor in the meat and the bacon caramelized in the Jack Daniel's was the most flavorful ingredient in the Indie Burger. My fries was a blend of fresh one with left overs, but the fresh ones was delicious, but very greasy too. They only make combos till 4pm, so if you want to have the burger, fries and soda, be prepared to pay the price of a combo and a half. The price, just normal compared to other burgers places in Rio, but not good at all for what they served me. I hope they can fix this problems but I'd not go back to find out.

Decent portion for the price, good fries, food does not that too long to come for an a la carte place. I have tried their chicken wraps and burgers with no complains. Was there last Friday and despite advise from a colleague who tried their prawns/shrimp cream cheese sandwich, i went with it anyways. Good amount of prawns, bread was OK... BUT SOOOOOOOOO MUCH CREAM CHEESEEEEE!!! Seriously, I think they put about 10 cubes / squares of cream cheese on a piece of ciabiatta. I guess for anyone is absolutely crazy about cream cheese... (and I do mean ABSOLUTELY CRAZY...) would I recommend this. Would still go back though, I still l like their burgers and wraps :)

Heard a lot about this place and the burgers were quite tasty. There's only three choices: regular,…read moremixed with bacon and a double patty, which makes the menu simple. They have a selection of Brooklyn beers which is nice if you're tired of Heineken. The fries were pretty crispy which was a nice since it can be harder to find. Their custom BBQ sauce was pretty good and that's probably what makes this burger special. The spicy sauce had a kick to it but not spicy enough for hot sauce lovers. This place is tiny! One big table inside, a few patio tables outside and the smallest of awnings if it rains. There were about 3 ladies who were busing the tables, they did not assist anyone is setting up a table or grabbing chairs and instead kept folding them away the closer it crept to 11pm, their closing time. They were already putting up the roll down doors over the place as they took the last order of the night. No need to stay open a little later since business is good even in the rain. Ps. officina del gelato is opening right next store!

So we decided to try this burger place this past weekend. It was a cloudy Saturday evening (around…read more6:30pm) so it wasn't busy. we actually missed the crowd (which was good, cause we got to get a table inside for the 7 of us. If you plan to go with a big group, there is seating outside (just hope for good weather). Inside, there are only seats for 10 people max (and its tight). so the burger: like Beco do Hamburger, they have two types of burgers: Hells Burger (made of beef rib meat patty) and Fifty-Fifty (half beef rib and half smoked bacon patty). I had the Fifty-Fifty and it was good. Had a bacon crust and a good serving, with melted cheese on top. if you are a fan of lettuce, tomato, pickles and onions and other garnish on your burger, this isn't the place for you. their burgers are simple and straight forward. They have two types of sauces ( Voodoo Barbecue and So Hot Its stupid), we didn't really see a big difference between the two sauces, and their Hot sauce, isn't really spicy (according to my spicy food addict friends). Their fries are traditional simple fries (on the thicker end, not skinny ones like McDonalds) but good. They had a special 2 for 1 beer special for the Brooklyn Stouts. Overall it was a good experience. If I am in the area and craving a burger, I'd probably stop by. But, is it a top favorite? I'd say I prefer the Beco do Hamburger ones better. But, go to Hells and give them a try!

Truly American 'style' food with interesting (and tasty) combinations. The burgers are good though…read morethe toasted buns do not hold up to the challenge of keeping everything together until the end of the meal. The night we were there they had live music and it would be good to have reservations on such nights. The waiters were very helpful to non-Portuguese speaking patrons with menus with pictures you could point to. The American style shakes were more than a little runny but given you only had paper straws (no spoons) in which in indulge it kind of made sense. Always interesting to see how another culture interprets your own. If I are hungry for an Americana 1960/70's style burger cafe you will enjoy Zack's. Definitely worth a go.
