Stumbled in here on a whim. I'd been driving by it wondering who would ever go in, because the outside is, well, extremely uninviting. (Note to the owners: please spend a little money on the outside of the place to make it look less dumpy - doesn't need to be fancy, just make it less seedy.)
Once inside, the decor is decent - pretty standard Japanese steakhouse. Service has always been very good, but that may be a function of the very small crowd they usually have (see paragraph one for my guess as to why).
Food has always been good, too - very good for Pittsburgh. Sushi is average, but good for the price, and the Korean food is very good, though a little inconsistent. (Bi bim bap has been average about 25% of the time I've been there and very good the rest of the time.)
