Happy to see that there was a vegan dish as this was my first time trying dry ramen. There was a long line outside but it moved quickly and efficiently. The Mushroom Aburasoba (vegan) was nice and filling. I added some extra spice which made the dish more flavorful and enjoyable. I wasn’t the biggest fan of all the pepper but I’m sure pepper fans would appreciate it. As you can see I enjoyed every bit of it but wasn’t a big fan of the raw onions

YUM! So good, we have been wanting to hear for so long and I am glad we finally made it. We came on a Saturday at 11:50am, and we didn’t wait long in line at all because we said yes to a table in the sun that others did not want, and it worked out great. Absolutely loved our food, the karaage chicken was good but we wish it had sauce. Both the aburasobas we got were awesome, we like the curry one the best.

There was already quite the line 15 min after opening so definitely set out earlier. Tried the original and roast beef aburasoba —both were tasty and filling. Their tamagoyaki was delicious, highly recommend. Overall, it was good but I really don’t think it’s worth a 30+ minute wait. It might be better for people who like spice since we didn’t order anything spicy. Takeout seems like it’d be more worth it.

This place serves up some really delicious aburasoba! I got the mushroom aburasoba and it was excellent! The noodles have a good bite, and you can add any extra toppings that you like. Never knew vinegar + chili oil would taste so good! Do try the chili paste and sesame seeds available on the table. They add so much flavor to the bowl.
This place always has a line but it moves quickly- we waited for ~15 min before getting seated on a Saturday afternoon and it was totally worth it!
I’d highly recommend this place and we can’t wait to be back!
