It would seem that it has even attained the status of a tourist attraction since at the entrance there is a sign in English directing you upstairs to the cake display. I didn't see any other gringos when I went upstairs, but the staff was not at all fazed by me walking around taking pictures.
I then went downstairs where a huge variety of breads and pastries are for sale.
If you have never been in a Mexican bakery, there is a procedure which you must follow. First you take a tray and a pair of tongs and put what you wish to purchase on your tray. Then you go to the lady at the counter who will write up your bill. You go to the cashier and pay for your goodies. Finally you take the receipt back to the counter, and your purchases will be carefully wrapped and packaged.
I gave in to temptation and bought a bag of pastries.
I left the bakery, and just a few doors down the street I came upon a shop selling marzipan. I looked in the window and thought about going in, but giving in to one temptation per day is quite enough.
