Cause the sheer richness of it will overwhelm you after the first. Stopping at one works here: the cheese fillings are thick, creamy, and super duper rich, held together by a flaky pasteis de nata puff pastry. Of all I tried, the salted caramel was my fave! The vanilla is good if you really wanna get the full cheese blast. Matcha and chocolate weren't too bad, but I found them so distinct flavours they kinda conflicted with the cheese.
