Boulangerie ichi who I visited at TBR22-1 open a store temporarily in ecute Shinagawa Station until February 1.
Sandwiched and sweets such as eclairs in a left showcase.
They highly recommended to get it immediately when you find it. There are three deliveries from a bakery a day, but it's not for sure, depends on how they are sold at a bakery.
There is a pile of Kouglof sale on a right showcase.
Kouglof is cake at Alsace area, where is a boarder of Germany and Switzerland, and sale which is salt, so i guess it's salty cake.
And what is in this showcase is...
This branch is open until this February 1. I'd like to get that roast beef sandwich by the last day!
