Celeiro.

It's a bit like Whole Foods, but Celeiro is supposedly the best place in Rio to get the best salad, according to Veja Rio, the magazine that puts out annual ratings of all the restaurants in Rio.

I went there after an incredibly long bike ride one day, to check it out. At 100 reais per kilo, it's super expensive-- you'll be happy to make out with less that R$30 worth of food on your plate. The salads are pretty interesting, but there not that much different from what you can find in the US, at Whole Foods. I won't be back, but the visit reminded me how much better it is in the US to find good quality, cheap food when eating out. People in the United States complain about prices, but they haven't lived in Rio.
