I was about to give 4 star until when we checked out we were "reminded" to pay additional on tip...
To the owner- Lady you really don't know how to operation business with customer satisfaction. Don't try to assume people bad by not paying certain amount of tip. In fact we were about to give a good tip and wrote a good review on Yelp since we were so excited finally found a dim sum place in Charlotte.
However, now you have an unhappy family left your restaurant who is writing a two star review and exploring other dim sum option now...
