Being fairly new to the Bay area, I haven't been to many
sushi restaurants here, but being a former frequent customer at Nozawa in LA, I can highly recommend
Yoshi-san's Monkichi (at 23rd and California).
Monkichi is a fairly small, low key place that serves up
remarkable sushi and cooked dishes.
Daily sushi specials usually include seared bonito, albacore, sawara (ono), scallop, crab, salmon belly, yellowtail belly, halibut, and uni, among others. Occasionally there may be sea bass, sardine, or live scallop.
On my most recent visit (this past monday) the albacore
and the sawara were truly outstanding. Also check out the Good Time Roll (shrimp tempura cut roll covered with albacore and drizzled with scallion, tobiko, and garlic ponzu), Poison (spicy) Caterpillar roll (with homemade
eel sauce), marinated shittakes w/garlic, gyozas, dinosaur feet (diced shrimp and shiso leaf tempura),
and the seafood salad, an assortment of fish with wakame
(sweet seaweed) with spicy chile oil sauce.
This is just to name a few things.
Chef/owner Yoshi-san is a very warm and accomodating. I recommend sitting at the bar, as he is the only chef
and wait times can get a bit long at the tables.
