I haven't seen the place in Causeway Bay, but the place in TST is ok. It is extremely good value for money, they use high quality ingredients, just the lacking experience makes space for some improvements. I have seen places far worse at 6 times the price.

There is one problem with the very friendly staff: They are so extremely unprofessional that it really hurts.

I have in the last 3 days told them 3 times to remove the flyers with the Causewaybay address. They would say sorry and when I pass next time the flyers are there again. Once out of these 3 times it was the manager I talked to.
I was so upset after the 3rd time, that I investigated the director of the company to complain there (The company register shows an address in London).
