"chef is still learning"-manager

We had an absolutely awful meal there (22.03). So did the table next to us (who also sent there food back). The manager said "The chef is still learning". Which is unacceptable for a restaurant like this. My burger first came raw. When it came back: it was a patty, a slice of unmelted cheese, and wasabi. Nothing else, the wasabi completely overpowered everything and there was no balance in the burger. My wife's steak looked like blade steak- terribly thing, stringy and tough. The table next to us send their meal back and also had a terrible meal. I work around the corner and am supremely disappointed at the quality of the food and manager. I would rather eat anywhere else. May be the vegan food is better- stay away from the meat as the may "still learning".
