거구장 (Geogujang) — the local verdict
Locals rate Geogujang 0.27 stars above the Google crowd — the 6th-widest local lean among the 17 badge-qualified restaurants in Insadong. The tourist rating of 3.6 is the low half of that gap, and a low tourist rating in Seoul usually means no English menu and no patience for confusion rather than bad cooking — locals keep coming back at 3.87. The local review base (716) dwarfs the Google one (121), so the local half of this gap is the better-evidenced half. The median gap across badge-qualified Insadong restaurants is −0.16, for scale.

Where the local verdict runs further ahead, within walking distance
Same district, a gap that runs further in the locals' favour, and a local score at least as high as this one — both conditions, so "locals prefer it" is a fact rather than a turn of phrase. Distances are straight-line from 거구장.
