I'm not exactly an expert on authentic ramen, but yum! We've ordered delivery from here a few times, and we've been impressed each time. It's a little bit expensive, but the portions are generous and the quality is on point. My husband pretty much always gets the Jigoku spicy ramen, so it must be good. I'm partial to the torikatsu (chicken) as far as protein goes, but I've tried it with multiple broth options. This is the only place I've ever tried tonkatsu broth and I love it, but the shoyu and miso are pretty delicious too. When you order ramen to-go or delivery, the broth is packaged separately from the "stuff" which helpfully prevents sogginess upon arrival. The only appetizer we've tried was the edamame and they were pretty tasty. It's kind of cool that you can get Ramune Japanese soda as well.
I plan to slowly make my way through the menu, and maybe eventually make myself venture from the noodle bowls to the rice bowls-- but it's hard to branch out when the soup is so good. I still haven't actually been to the physical location so I can't tell you anything about atmosphere or service, but I can wholeheartedly recommend their ramen.
