Noodlecat understandably has an identity crisis on Yelp. I've found it to be a bit of an acquired taste as I like it a little more each time I go. Everything from the decor, atmosphere, food and clientele are a little different from the typical restaurant in the area, however given the chance, I've found most adventurous eaters learn to like Noodlecat and its unique offerings (to Cleveland).
First, Noodlecat has an excellent happy hour. $1 Black Labels, $5 half-portion noodles, 2/$5 steam buns and $3 Sapporo drafts are all excellent values for the surrounding area. The happy hour runs until 7 PM. and usually draws a good crowd. It's also a good way to try Noodlecat for the first time, as you can get an assortment of items from the menu to try to figure out what you like.
In terms of food, I've found different menu items have a strong following depending on individual tastes. My personal favorites are: the spicy octopus stir fry udon, the pork miso ramen, the pulled pork steam bun, the Japanese cobb salad, and the butcher's bun special. Most everything they serve has a very unique flavor with very interesting combinations. Also the vegetarian daily special is very popular with several vegetarian coworkers.
