some time ago Monica Eng wrote that one of her favorite S&P shrimps around twon was at Sun Wah. For some reason I've never had that dish there, as I'm usually grabbing stuff for takeout but it might be a good option to try. I'm usually pretty happy with what I do take out.
at Silver Seafood, I'm not as fond of their shrimp, but their S&P cuttlefish has at times been really outstanding.
I'm also a little surprised by the recs for nhu hoa's Shrimp. I like Nhu Hoa quite a bit but have always found thier shrimp dishes to be a little off, just not all that fresh tasting and have stuck with land animals there.
