Looking for a fun sort of romantic lunch spot downtown, possibly with an option to dine al fresco (tomorrow/Fri. 6/29). I heard about Plouf, but just read some not-so-great older listings about Plouf being loud, crowded, overpriced. Can anyone recommend it as a good lunch spot? If not, how about something between there and the Embarcadero for good meat and seafood (even if not al fresco)? Thanks so much in advance, SF foodies!
