This restaurant was recommended by hotel staff. They said it doesn't look so great from the outside but the food is wonderful. They were spot on. Osaka serves Korean, Japanese and some "American" food. The portion sizes were filling, no one was able to finish there meal. There were 4 of us having 4 different Korean dishes. All of the dishes were great. Wait staff were attentive. They only had 1 waitress covering at least 6 tables, she kept up with all tables. Additionally, she made good recommendations. Now, the bad things - the furnishing are coming apart. We sat in a booth that the vinyl had ripped and was taped back together. The tape looked like it had been there for years. The whole place looked tired.
