You can enter via the main Mitsuwa Market entrance, then take a left to find it.
Parking is plentiful in the outside lot.
There was no wait when I arrived around 2:30 on a rainy Friday.
A few nearby places worth checking next.
I have been using it now for 3 months and it saves me so much research. Reduces the need to call and double check every time.
How did I not know these places existed?! Atly's scoring is a lifesaver, now I can finally find THE spot without wasting time Googling my life away.
