After years of craving, I finally tasted their sans rival and silvanas so I also agree with other reviews, it is a must-try and a good pasalubong if ever you will visit Dumaguete. I tried the ube but I prefer the buttercream flavor, but you can also order pandan, strawberry, and chocolate flavor. The sans rival is also good and budget-friendly pa.
Since I live in the province, I have no idea that they already have a branch in Metro Manila, thanks to @purpleplumfairy for the information. I don’t need to travel to Dumaguete if I’m craving their cakes and pastries. According to my research, it was year 2008 when they opened their first kiosk in Food Choices, Glorietta 4 in Makati. You can also buy in Shangri-la Plaza, Robinson’s Magnolia, Sun Valley Paranaque, and selected SM Markets. I don't know the mall prices but I have a feeling, mas mura sa pinagbilhan ng friend ko "Silvanas from Dumaguete" (check their Facebook page).
Update November 2021
I was cleaning my phone gallery and I found these photos. It’s been months since the last time we ate silvanas so when my husband asked me if I want silvanas, I immediately said yes. He was in Shangri-la Plaza and he saw the Sans Rival Cake and Pastries branch. He sent me some photos so I can choose.
He bought Pound Cake PHP250, Silvanas PHP260, Josephines PHP30, Blueberry Cheese Cupcake PHP65. The “Josephines” is the inspired version of Napoleones of Bacolod which is made of layers of thin puff pastry with sweet filling and confectionate sugar. The taste is okay but I prefer the Napoleones that I’ve tried when we went to Bacolod. The pound cake is okay but my personal preference is sponge or chiffon cake. The Blueberry Cheese Cupcake is good, bitin lang at maliit lang yung cupcake.
