There's almost always a wait outside, even at lunch time, but the wait is very short. When we got there there were 4 people in front of us but we only waited for 5-10 minutes before we got seated.
Both my husband and I got the Tonkotsu Black Ramen because i saw reviews saying its their best dish.
Tbh it wasn't anything special.
Its a nice light ramen (not as heavy as kinton), the broth makes you want to finish the entire thing while at kinton after eating the noodles and pork you don't want to finish the soup.
The pork isn't as good as kinton though, which was disappointing.
The portion is just right for lunch, but if we were to have dinner there we wouldn't be full from just one bowl of ramen. You would have to get some side dishes.
Overall, i would come back for lunch if i was in the area and didn't know what to eat.
