Wonderful Patisserie, NW9 6LH
As of September 2017 the furniture remains inside photo taken through window and there's a sign in the window photo claiming that it's just closed for refurbishment and will be opening again soon, but a staff member at the Bang Bang branch confirmed to us that it won't be reopening.
The information below is retained for historical purposes.
Inside, there's a fair bit of seating, a freestanding display of sweet and savoury Chinese bakery items, an ice cream freezer, a display counter of decorated cakes, another display counter with various flavours of mochi, and a few shelves of snacks and sweets (including fried snack seaweed and pocky). You can buy the pastries and things to eat in or take away. They also do various drinks including teh tarik (pulled tea) and pearl milk tea (bubble tea).
Kake visited in September 2009 and tried various pastries (fine) as well as two flavours of mochi; chocolate (bland, not very chocolatey) and peanut butter with brown sugar (tasty). I was specifically looking for pork floss buns, but they don't seem to sell them. I liked the mix and match nature of the mochi counter though, with each piece priced individually (starting around 80p).
Accessibility: Three steps up just inside the front door. Didn't check the toilets.
