I read somewhere that this is owned by a Japanese couple whose first venture is somewhere in the south. They recently opened a store in Makati (near New Bombay, which is how I stumbled into said establishment) for a bigger market.
There are so many varieties to choose from. The small cream puffs are P20 apiece, and range from original (sugar coated) to more exotic ones like cocoa power and dark chocolate with almond. We tried the dark chocolate with almond and white cholocate.

The flavors aren't so present; the chocolate doesn't taste like chocolate-- just cheap flavor coating of some sort. Then again, perhaps it needs to be sweeter to make the flavor distinct. Since the puff is not sweet and filling isn't thick, you won't feel so guilty afterwards. This isn't necessarily a good thing, since the tendency is to go for another piece because you didn't feel that heaviness which desserts provide to signal the end of a meal. For curiosity's sake, I'd say P20 is cheap, but for how it tasted, it's too expensive. Good thing I'm still not a fan of cream puffs.
The bigger cream puffs are P35 apiece. There are also elongated varieties such as the eclair, and cream puffs with whipped cream and fruits. Apparently, the Japanese like their puffs with whipped cream. It's good to know there's this Japanese variety for people to try (cultural enlightenment, people!). I''m sure Beard Papa isn't too happy about the news of competition though, as it doesn't seem to be doing well as it is.
You can buy a box of assorted cream puffs for P180, or opt for one flavor in boxes of 3, 6(?) or 8. I get why it's called Happy Cream Puff. Just look at that picture! Anyone who receives this box as a pasalubong won't be able to help but smile.
