Found it! (Had mis-written the address and it's about as noticable from the street as Saito's...) Had 5:30 (opening time) reservations, and there was a party of four at the bar already when we arrived. Place was full by the time we left; the two of us were apparently the only customers not fluent in Japanese.
We ended up with "new young guy" (who was wearing a name-tag, the first I've ever seen on a sushi chef, and I've now promptly forgotten his name) instead of Shibutani himself. "New guy" was very pleasant, but had as pegged as gringos (judging by his omakase) until I discussed with him eating in the old Beverly location, Katsu when it was in Silverlake, etc., and also inquired how the kohada was, at which he brightened up considerably and began pulling out more interesting things.
Fish wqas wonderful, price is so low as to be almost unbelievable...
I'm going back.
