Went to Osaka's on a Wednesday evening. It was around 9:30 PM, kind of a late dinner so it wasn't too busy. The place was quaint, peaceful and the service was pretty good. I ordered the chicken katsu which wasn't anything out of the ordinary and a beer on top of that. The prices are decent, the staff is friendly. But I was kinda looking for the "A-Ha" factor here.. and it never showed up.
Overall, good experience, but if you're looking to be blown away.. I'd do a little bit more searching.
