I just checked out Chukasoba Uemachi after hearing some good things about their Shoyu ramen from 5am Ramen. It was pretty good but didn't blow me away or anything. It's definitely better than a lot of other Shoyu ramens I've tried, but it didn't really stand out as much as I hoped. Maybe I just couldn't pick up on all the subtle flavors.
Also, there was about a 30-minute wait and it's a bit out of the way. If you're short on time, you might want to skip it.
