I was here twice. the first time I didn't like the rams at all. when I ordered the second time, sans paprika, I was so much happier. made slightly vegan. not authentic, but super solid choice when they go with not veggies. I loved the mushroom bao, could go back every time and leave it satisfied for just the bao.

The vegetarian ramen can be veganized by warming out the regular noodles for gluten-free!

They can get vegan rams, only safe to tell them because they need to use different nudes. for me it was a little too filled with sweet, I would have less sweet and more tofu preferred, but I am a tofu lover. the servier sizes are huuuge, but unfortunately the nudes break into small mushy pieces when they store it for the next day. all in all, I would go back to try.

Cool ramen spot I've been looking to try for awhile. I decided to forego eating my body weight in sushi this trip and went with something warm for a cold and rainy day. I stopped in for a lunch on a Friday afternoon and it was fairly busy. I sat myself at an empty spot towards the end of the bar. It was giving off izzy vibes with the dark lighting and group seating. Ordered a Sapporo while I decided what to eat. The duck bun was a must, and an excellent starter. I ended up with the spicy paitan shio ramen. Huge chucks of pork belly too tender to pick up with my chopsticks. The broth was excellent, not too salty or spicy, and had me drinking straight from the bowl once I finished off the noodles and toppings. And may I say that was the best soy egg I've ever had. Perfectly cooked, I would be good with just those, noodles and broth. I enjoyed both the ramen and watching the staff work their magic.
