What happened when I visited Ka Chi with two friends was appalling. The owner made a HUGE SCENE.
I'm not sure what his problem was, but he started yelling at these two young girls sitting at a nearby table. He was threatening an intimidating them. I was in shock that he would behave like that at all, let alone in his place of business which was packed with customers. The room went silent, everyone turned at looked at the two girls and the owner/manager yelling at them. He was pointing and waving his hands barely an inch from their faces. The girls looked very uncomfortable and did not say much back to him. They tried to speak quietly, but he kept yelling. He was being very aggressive. The servers looked embarrassed and just kept moving along. I got the impression that it was not the first time they had witnessed this type of incident.
After about 5-10minutes of that awkward situation, the he just headed behind the bar, and gave the girls glaring looks. They left quickly, and surprisingly still paid their bill. I would have called the police if I were them. His behaviour clearly made EVERYONE UNCOMFORTABLE.
The food was good and well price, which is unfortunate because I will never go back there.
I would not recommend this place since I do not think that such a wretched person should have their business supported. Also, I wouldn't risk witnessing that again only to have my stomach turning.
