HOWEVER the doorman didn't greet me, instead an A4 notice acrylic stand apologising for their off day (of all days!).
Feeling flustered, I hurriedly texted my friend who was on her way and a couple of minutes later, she appeared to suggest a plan B.
We then decided to cross the road to have fresh Market O brownies but when we got up to their restaurant, Natural Kitchen - brownies we non existent (it was on the menu months ago according to my friend who frequent the place).
So instead we settled for their lunch course/prix fixe which turned out to be a delightful pick in the end.
For 25,000won per pax- it was a steal at this upscale part of Seoul.
