I ordered the Tonkotsu with thin noodles ($10.50). There was a line up when we came, but turnover is fast so the wait wasn't long. The fast turnover is highly due to the fact that they clear away your bowl immediately after you finish and ask if you want anything else, prompting you to either order dessert or simply ask for the bill. I'm not a huge fan of this as it makes me feel a bit rushed.
The food came quick and the noodles were good. I love the eggs and pork belly that came with it.
Will come back again if I want ramen.
Also, I overheard the table next to us ask the waiter how big a serving the extra noodles were and she said it's as much as you get in a normal bowl of noodles. So if you're a big eater, it is definitely worth it to pay the $1.50 for extra noodles!
