Bake Ur Day is quite renowned for its Vegetarian Cakes. They have a wide variety of cake options in Chocolate and Fruits as well.
Some of the unique flavours of cake I found out was Chocolate Berries Chocolate Casatta, French Opera which is a combination of different chocolates, Italian Truffle, etc.
Also, their fruit flavour cakes are quite innovative like Apple Caramel, Fruit Opera, Cranberry.
They also have Indian flavours like Rasmalai Cake, Pan Pasand Cake, etc.
They also serve cheesecakes. In all, I found the service is very quick, quality is very good, and the prices are quite reasonable.
