I've been here many times since their opening. It doesn't taste as authentic as other places in the area, especially their onsen tamago (bland), but there aren't that many alternative ramen shops to choose from in the first place.
Fried oysters and noodles are fine, but the broth is very salty most of the time. I end up needing to drink lots of water an hour after the meal.
The place is pretty busy with little room to wait for a seat. You'll have to try a few times in order to get a waiter to your table.
