A small little retail spot on a side road slightly estranged from the main Kyunglidan strip. The bottle shop probably gets more love than it deserves due to the fact that it's the only one around in the area and it seems to keep a decent stock of whatever is in demand, but general impression about this place seems to be either a hit or miss between its patrons; those that have lived long enough in Korea to appreciate the small business model and the establishment for what it is, seem to like the fact that you can purchase your beers from inside the shop, take a seat outside and drink your troubles away while staring at the sun setting behind Namsan tower. To those whom the former statement doesn't apply, they're usually turned off by the fact that beer here is a bit less affordable than its next door neighbors. (Woori Supermarket, the Booth, Magpie ITW)
Objectively, the Bottle Shop is slightly on the pricier side, but still cheaper than ordering bottles/cans at any other craft beer establishment in the area. They occasionally stock brand new imports, but aren't too quick about cycling their products. (you'll know that they're cycling if you find an ice cooler outside with some beers for discount) The owner, Nick, comes around every now and then and strikes up a conversation, offering discounts and whatnot, but otherwise it's not all that different from your typical craft beer bottle shop in the states. The staff is responsive and helpful if you have no idea what you're doing, but they do have a tendency to roll their eyes at you if you ask about "x beer" that is not yet imported to Korea. (even though they display beers like that in abundant fashion all over the store as decoration)
All in all, a well-executed, "authentic" take on what a bottle shop actually looks like back in the states, but heavily limited by the availability and market trends of importations.
