One of my Cleveland favorites!
Noodlecat has nailed "Clevanese" down to an art form. They take Japanese-inspired flavors and execute them with a strong commitment to locally-raised and locally-produced foods.
Their house infused draft Sake is delicious. The spicy octopus udon stir-fry is great. As for portions, I have never needed a whole order of noodles there. I typically stick to a half order of noodles, a couple of steam buns, and some sake. High quality food for a pretty great price--especially during happy hour.
I have never been disappointed at Noodlecat
