I read J.G.'s review in last Thursday's L.A. Weekly and had to check it out since I was only ten miles from there at lunch time. (Well, actually I still had to wait for twenty minutes for them to open since I got there at 11:10.)
It was very worth it. The best ramen I have ever had. I chose the "A set", which had some gyoza as a side dish to the pork ramen bowl. I also ordered the codfish roe as a topping. It was stupendous.
All I can say is go there! If you're anywhere near there with a craving for ramen, this is the place.
I can't much elaborate on Jonathan Gold's review except to say that he got it totally right.
So, read the link below and go!
