You don't have to go to Santa Barbara to get the Uni.
All the best sushi bars in LA get there Uni from Santa Barbara.
I heard from a person in Ventura that you can get Uni directly in Oxnard. You might want to try these two places.
1505 Mountain View Ave Oxnard, CA 93030
1-805-483-8555 FAX 1-805-486-7167
398 Kalorama St. Ventura, CA 93001
First, I would repost this on the California Board so local Santa Barbarians can offer help.
Second, if you are willing to go to the Port Hueneme area (which is occasionally discussed on this
board), seek out:
457 W Channel Islands Blvd
Port Hueneme, CA 93041
A little gem in a non-descript ultra-suburbia TGIF-strip mall. Bar seating is omakase only. Call ahead
to see if they have local uni (I believe harvesting season ended at the beginning of April)
