Had this twice and not been impressed either time. Maybe I'm not the right person to judge since I'm not very familiar with cheese tarts like this but I didn't enjoy the texture or flavour. The crust was tasty, but I really did not like the gelatin topping. It made the whole thing feel slimy. It does not last very long in the fridge either without becoming mushy.
I also got to try to the mochi strawberry tart and it was more my style. It had a very distinctive sugary and artificial strawberry jam sort of taste but I like that sorta thing so I enjoyed it.
I'll stick with egg tarts from local HK-style bakeries instead.
