I was curious about Yoshida, and a group of us tried it about 1 month ago. In a nutshell:
* Yoshida was THE WORST Japanese restaurant I've been to in the last ~7 years, hands down! :(
Their sushi (every piece we tried from Hamachi to even the Toro(!)) had "tendons" in them. Of course it's unfair to compare Yoshida with the best places around, but after I've been to legendary places like the famous Sushi Nazi in LA, why do I need to suffer this mediocre sushi?
Yoshida also claimed they had *real* Kobe Beef (flown in from Japan), so we had to try that. At $35.00 for a small plate (a few slices!) we were soundly disappointed. The beef was VERY chewy and hard to eat... a slice of plain ol' Rib Eye Steak from Morton's, Ruth's Chris or Palms would TROUNCE this stuff.
The Ankimo (Monk Fish Liver) was SO fishy none of us at the table could even finish our first piece.
The Service was horrendous... there were like ~4-5 waitresses serving us (randomly floating between tables), and with that many waitresses, we had to ask at least ~4-5 times just to get served Tea (and it happened again when we asked for refills on the Tea).
The Tonkatsu (breaded pork) was like a BLOCK of Hard Rubber (no joke). We couldn't even finish our first bites on that as well.
There are FAR better places to go to like Japon Bistro (Pasadena) (which is really close by where Yoshida's is anyways), or even basic places like Kiyosuzu on Baldwin. Or just suck it up and go out to LA and get some real sushi. :)
Yoshida rating: 2.0 (out of 10.0). HORRIBLE.
