Went to the Samseong branch, quite close to COEX.
We arrived early because we went to a COEX exhibition and hand't eaten lunch. When I smell the restaurant I almost crawled there! There were not many people at that time, but the place got full as we ate.
Hamburgers were tasty, but I give the patty a 7/10 because it wasn't very juicy. I ordered the simplest one, as usual, and the BF ordered their CREAM.The chilli fries were also good, with slightly spicy chilli.
Even though we were both starving before eating, we got really really full. That plate of fries was really big for 2 people!!
I would come back again, but hey... SEoul actually has many good burger places... I'm starting to have a ranking list in my head!
