Songridan-gil — café and restaurant alleys between Seokchon Lake and Songpanaru Station, a converted residential neighborhood
Lotte World Mall dining floors and the Lotte Department Store food hall — easy picks right under the tower

The Seoul Sky ticket desk is deep inside the mall and signs are confusing — budget about 20 extra minutes from Jamsil Station.
Weekend late afternoon (around 5–6 pm) is the peak; going about 1.5 hours before closing is quieter. Tickets are usually cheaper booked online.
