I come to osaka often now, lately at least once a month, so I feel I need to upgrade them to a 4.5-5. Their service and food is pretty consistent, but the reason I'm upgrading their score is because of the servers. They are always very courteous and come by to refill drinks at least twice each time i visit. They even have tolerance for the lurkers... you know, those people who stay at the restaurant way past the time necessary after eating there. (I, unfortunately, know this from personal experience... thank you for not kicking us out!). So a shout out to the workers at osaka!
