Walk out, take a left at the intersection you can cross the street at a diagonal, do that.
Foody Goody is on your right hand side not too far down BUT it looks like you are going into a parking garage - because you are (see 1st picture below). There is an attendant and he will steer you ro the right where you go into the building (second picture) and go up the stairs to the 2nd floor.
I'm pretty sure this isn't safe to US standards, but I LOVE it!
So, continue walking in the direction you were going when you went to Foody Goody.
Walk, walk, walk till you come to a pretty big (but not too big) intersection and turn left ( you will see all kinds of activity on this street) and commence shopping! This is a quaint little neighborhood market street where you can get all kinds of goodies from plants to toiletries to food - I saw 2 butcher shops and a bakery and couple of food markets like the one pictures below to all kinds of cute little cafes.
OH MY GOODNESS...I'm in LOVE with it!
I can't wait to take my MIL here when she comes to Korea this fall!
I love it!
