“You can assume that those coming after work will almost never be able to buy it.”
On the 9th, an official at the Pizza Seolgi pop-up store in Yongsan IPARK Mall, Seoul, commented on the popularity of Pizza Seolgi in this manner.
Visiting the scene on this day, even during a quiet weekday period, it was frequently observed that passing citizens would stop to look and proceed to make a purchase.
The pop-up store official explained, “On weekends, there is high foot traffic, with thousands of customers visiting,” adding, “Particularly last Saturday (September 5th), when the fireworks festival was held, we believe about 10,000 people visited.”
