Supermarkets

The 2 biggest supermarket chains in Porto Alegre are "Zaffari" and "Nacional".
Zaffari has bigger shops that are called "Bourbon" and Nacional has "Big". Nacional was recently purchased by Walmart. On this Nacional site, it is possible to buy groceries on-line.
Both supermarkets are good and each specializes in different areas.
We think that Nacional is better for imported foods, while Zaffari has a bigger verity of foods in general. The best Zaffari store that usually has everything fresh is the one on rua Plinio Brasil Milano. The best Nacional store is on rua Lucas de Oliveira.
Important: Only Nacional accepts credit cards. Zaffari only accepts debit card or cash (of course...)
