Seth,
I drove along Canal last night on the way to a mediocre dinner at Moon Palace, and was surprised that so little of the street was torn up. Last time I went (around early Feb, I think), I was so bummed by the number of places that were closed due to construction, that I haven't been back is over two months (!)
To the best of my knowledge, and quite counter-intuitively, Manolo's is run by the sister (and features the Masa Madonna) and Rubi's is run by the brother.
I've been very happy with large produce purchase about 80% of the time -- if you do get the berries or other bulky fresh items, consider pulling up right in front and loading the stuff in (rather than carrying it out of the market by hand...but you probably already knew that).
