I've been going to Osaka for sushi for 20plus years and I love their food however in the service industry "service" is everything and so the single star tonight is for the service we received. My daughter and I were craving late night sushi so we googled Osaka which stated they were open until 1am. As we anxiously entered the restaurant we were met by a very curt young man with light hair and glasses who immediately said, "we're done!" We weren't sure what he meant and so he repeated we're done to which we asked if he meant they were closed. All we received in response was a "yeah" and nothing further. Wow! So unfriendly and unprofessional. Hopefully this employee will receive some customer service training soon before he drives away all their long standing customers.
