Metamorfose

Very nice place with tasty set dishes as well as take-away (like esfirras and other versions of Brazilian snacks). Friendly ownership and staff. Note that it is on the second floor of a building and a bit hard to spot, but you will see the sign if you look up. Just enter that building and take the narrow staircase on the right.

Mostly vegan except for an occasional fish dish and a few other exceptions.

Finally, they're open on Saturdays.

strangely, my companion was being served at the counter , but she was abandoned for 5 minutes by the woman dishing up the food....wait for it..in order for the server to answer the restaurant telephone..it took a lot of questioning to work out whether there was a buffet or not, a la carte, or what.
Food was good but i didnt like the set meal type setup....some of my dish wasnt too tasty...a hair in my companions dessert....good food , macrobiotic...

Macrobiotic self service club with daily changing menu. Suitable for vegans as well. The food was very tasty (try Banana Cake!). Super small terrace. Nice and friendly cook/waiter/owner and other club's members warm & willing to convert you. No english. Very different to rest of Rio!
