There’s a sweet old 아줌마 who makes me feel so loved and appreciated

every time I see her. She doesn’t speak English but a friend translates and she calls me baby face, touches my shoulder affectionately every time she sees me, and looks at me adoringly like I was one of her own kids. It makes my heart melt, and I really want to do something nice for her. What would a sweet old lady love the most? I always see her at her work, so I was thinking about surprising her with a box of baked goods to share with her colleagues who are always so nice to me as well. Can anyone recommend a really good bakery in Gangnam? Should I get them all cookies, cake rolls, etc, or do you have a different idea? What do you think is best? Thanks!
