"Visited a couple of year's ago and discovered the revelation that is an oyster on hamburger! Hamburger was cooked to a true med-rare as ordered not overcooked like most places) and topped with a plump, flash-fried oyster very lightly battered) that pleasantly melted into the sandwich with my first bite. I remember those details bc since then I've debated coming back, not wanting to ruin that specifically delicious gastronomic memory. I broke down and risked it today while visiting SF, and remain very happy! Oyster was not as plump, but then not all oysters are created equal. Nice hint of horseradish in the aoli. It's more costly than I usually spend on a hamburger $18), but the meat is fresh, local and totally worth it. Comes with a tasting of their cole slaw, so I didn't really need a side order of anything. Plan to return tomorrow b4 leaving town bc I want to try their liver and onions."
