We finally headed down to cafe cakes after reading about it on chowhound! Wanted to share some photos :) thanks to noriko (the owner) for allowing us to take them! I really really liked the place and she makes some delicious cake.
The link is attached.
(not sure how it compares to Japonaise bakery in brookline though? I've only had the cakes/buns sold at the porter square booth but never actually ate in the cafe itself. btw Japonaise makes the most delicious azuki buns!!)
