SF Eats: Okane
I went to Okane on a weeknight around 7, so it wasn't too busy. That might also be because it's located in SOMA around the Caltrain area where NO ONE goes after the work day is done. I was pleasantly surprised to find that it had delicious food though!
My favorites were the chawanmushi, oysters, and Ginza rolls, but I'd recommend skipping the steak and the fried fish (some kind of karaage).
Honestly, the oysters were so good! I'd go back just for those
