Went on a Wednesday afternoon and waited approximately 20min for a cheese tart. I agree with other reviewers that there were a lot of already baked cheese tarts available yet there was a lineup of people. Although the staff is friendly, service is inefficient and slow.
I ordered the regular cheese tart that was already boxed and ready to go. When I tried it about 2 hours later, the crust was soggy and part of the glaze had shifted off the tart and onto the bottom of the box. I think this happened because the cheese tart was boxed when it was too hot and created steam in the box.
I have also tried Pablo in Tokyo and the quality and taste of the cheese tarts tastes much better there.
