It's been open 6-7 weeks. Ate there a little over a week ago. It is a traditional sushi-only restaurant, run by one of the main chefs who used to work at Hide on Sawtelle.
A bit pricey (around $2.20 - 2.50 per piece, 4.50 - 5.00 per handroll), but everything was fantastic. The albacore was incredible, and the scallop special handroll is amazing. The yellowtail was excellent, the unagi was very fresh and the sauce not too salty. The spanish mackeral was also a delight.
Everything is prepared perfectly. The rice is a bit warm, the fish is cold (except for the unagi).
When we went, they still didn't have their liquor license. But it is coming soon. They will have Kirin on tap, and sake.
For reference, we love Hide and Sushi House (on Pico) as affordable but good sushi. We also like Boss Sushi on La Cienega (run by the former Sushi Kokyo people). But the quality at Sushi Zo really surprised us, and ranks among the top (not counting Matsuhisa). I don't care for Sasabune as much as most others on this site.
