Dropped by Yuzu ton 37th Ave San Mateo to try them out for dinner earlier tonight. Was surprised to find that it was in a location very similar looking to 25th Ave. Basically small businesses located on both sides of the street.
Yuzu has a very small interior, very intimate setting with maybe 6 to 7 tables, and a small sushi bar that sits around 6 people.
Started off with tai and hirame which were quite nice. Yuzu is the 2nd restaurant owned by Hiro-san of Sakae in Burlingame so the same fish supplier is used. Prices were more or less the same as Sakae's though I have to say the same fish seems to taste better over there!
Next I had the grilled oysters with mayonaise sauce. This was a little overpowering (the sauce) even though I emptied the entire lemon slice/juice over it, though it was a nice touch.
The saba was nice and oily, and the uni was a bit on the cold side as it came directly from the refridgerator. I finished off the meal with a appetizer order of gyu-tan shioyaki (grilled beef tongue). There were 6 good sized pieces in there, seemingly thick, but juicy and bouncy to the teeth/chewey (Taiwanese people commonly refer to this texture as "QQ"). The only thing I would have preferred is if they sliced up the gyu-tan thinner, much like yakiniku style, which would have been a betterexperience. Unfortunately most Japanese restaurants don't do this (except maybe at Juban), so if you get a slightly thick piece of gyu-tan, you have to hope that it is not overcooked otherwise it will an exercise on your gums ;-).
The sushi chef at Yuzu used to work at Sakae, and has since moved to work at Sushi Kei and then Seto Sushi in Sunnyvale. He definitely has the skills and the experience.
Checked the menu and they offer similar fare to Sakae, although concentrating more on grilled items/small dishes such as scallops, asparagus beef, organic chicken yakitori, stuffed shitake mushrooms, and many others, though they range from $6 to $9+ (similar to what the higher end izakaya's charge).
If you like Sakae, then you might enjoy Yuzu as well. It is not really an izakaya by definition but comes close. I guess you can call it a bar & grill type of place. However if your first love is sushi then Sakae would be more appropriate. After all Jun-san the kaisei chef king, and iron chef of small dishes, works there! ;-)
