Asahi Kuronama in SF: Murasaki, Koo, or other?

[njfreqflyer]

I will be visiting San Francisco for the weekend of July 12-14. A little known benefit that the West Coast has over the East Coast is the ability to get Asahi Kuronama, a black beer brewed in Japan and distributed in California. In my opinion, this is a great beer (see my recent post on the topic here: http://www.chowhound.com/topics/528842) and one of my goals for my visit it to make sure I get some Kuronama.

Through Google, I’ve found two restaurants in SF that supposedly have Asahi Kuronama: Murasaki and Koo. I see that both have favorable reviews on this board, and the $80 omakase at Koo (described here: http://www.chowhound.com/topics/36989) sounds pretty good.

So, could I please get your help in picking one of those, or maybe you know another place in SF that has Asahi Kuronama? (Does anyone know a liquor store that has it?

)

Selection criteria, in order of importance:
1. Asahi Kuronama
2. Quality of fish (and rice!) and preparation
3. Bonus points: special fish and dishes not widely available
4. Bonus points: shishito peppers

Rolls are not important to me, and for this trip price is not a factor.

I’m flexible on which day or night I go (Saturday, Sunday, or Monday), so please let me know if you recommend one over another, and whether reservations will be required.

Thanks!

Koo won. The Kuronama and sushi were delicious. See my post here on the meal: http://chowhound.chow.com/topics/36989
