My favorite ramen spot in Denver. Been here a dozen times or more and it never disappoints. The tonkotsu is always amazing. Tried the birria ramen on our last visit and it was definitely worth getting. If you go, save room for dessert. The mochi donuts are to die for.

Delicioussss Birria ramen! They don't do reservations for fewer than 6 people but we were sat immediately on a Saturday night at 830p. You head downstairs off the street into a cute spot with an open kitchen and ramen bar. For apps we had the pork gyoza, spam musubi and spicy green beans -- all delectable. Had enough room left for half my ramen which was amazing, wish it had a little more meat but that's no surprise. Stuffed myself with the dessert- the loaf cake with brown butter glaze and earl grey ice cream, honestly delicious. My bf said this is the best ramen in Denver. I'll have to try others to see now that i moved here but this was a fire place to start. We'll be back soon!

Cool basement restaurant with cement bar and cool lighting. Simple menu with bento boxes and ramen. Even 25% off all cocktails on Thursdays!

YUM! My son and I were craving vegan ramen and decided to finally try Osaka. We're thrilled we did, and will be back. We went on a Saturday night around 7. It was definitely crowded there but we were able to get seated without reservations in 20 min. It was cool to see what a popular spot this is, and after tasting their food, we can now understand why :) The location is nice around the McGuckin plaza in Boulder. I wish they had a patio, but it does look like they have a sun room area with big windows that open. The ordering system is cute with a little controller on your table that you push when you need your server. It's really efficient and worked great. We got the Agadashi Tofu as an appetizer (sooooo GOOD - be sure to order with vegan broth if you're plant based), and each got the vegan ramen. My son's face was so cute after his first bite of the ramen, he was hooked. The vegan ramen broth has a great flavor, we loved everything about it. So excited to have a wonderful ramen spot in Boulder as new go-to.

I think overall this is a pretty good ramen place, It's not the best I've ever had but it still hits the spot and is perfect for a cold night out. We came on a weekday night and got seated right away. I got the tonkatsu ramen and really enjoyed the broth. It tasted super savory and meaty without being super salty. The soft-boiled egg and the meated were also cooked perfectly. The pork had a nice char but was still tender. My only complaint would have to be with the noodles - I feel like it was a bit soft and didn't have some of the chew that I usually look for. Overall, I would recommend the spot if you are around the are and craving something warm.

Phenomenal ramen! Everything from the broth, to the ingredients, to the egg was very authentic. Our waiter was exceptionally friendly and very knowledgeable of the establishment. The seating arrangement was comfortable and modern. Definitely great for a hot date, or quiet evening with a friend. Cannot wait to visit again.

Pretty decent place for Ramen! Tried the spicy miso ramen with extra pork belly, which is nice and thick and has a good char texture on there. waaaay better than most other places that seem to serve it as anemic-looking. so waaay more appetizing here. Only downside here honestly is the chairs at the tables...they are waaay lower than the bench side of tables so just creates an odd seating area. recommend sitting at the bar here. Finsiehd off wtih the mochi donuts and they were pretty good! not sure if i would order again, kinda salty/sugary so if thats your thing go for it. just make sure they changed their fry oil recently cause we could taste it. But the saving grace here is definitely ramen. stick to that!
