This is the first ramen shop I've been into, and I'm a fan. Their Ma La ramen is my favorite there, followed by their Red Miso. The portions are huge and satisfying. It's an interesting place to eat at; there's anime playing on projectors and in low-lighting.
Only downside is when I've been there, they are a bit slow to seat and serve you. I noticed that they seemed understaffed- last time I was there there was just the barkeeper and a waiter. But that doesn't take away from how good the food is!
