Bought a great Monkfish Tail at Yum Yum Fish on Irving between 22nd and 23rd this weekend. They have quite a selection of fresh fish. It's as good a fish market as i've been to in SF. Plenty of selections as well. And to top it off they have a sushi bar as well for take-out or to eat at the 3 or 4 small tables in the storefront. It isn't much for ambiance, but the sushi looked good and cheap. It's the new 'spot' in the beautiful Sunset.
