I've recently moved to RI, near East Providence, and would like to learn about Portuguese cuisine; I know next to nothing about it. I'm looking for suggestions for sit down restaurants, carry out places, holes in the wall, groceries, street food, bars, anyplace to try this cuisine which is new to me. Any good places to enjoy Portuguese table wines by the glass? Great place to buy linguica or churico? Are there some classic dishes I need to try? Any noteworthy Portuguese cheese? Thanks for any advice.
