Ordering food in korea
I'm currently in korea and i barely manage to order food but I still need help with some things like when I want to change the size and those kind of things. My korean level is still pretty low. So I would appreciate your help. I would like to know how to say:
1.- to eat here. ( It only comes to my mind saying something like 여기에서 or when they ask me for take out say: 없어요.)
2.- _____ change to large/ small size, please. ( i wrote something like: ____큰/작은 사이즈 변경해 주세요. But I don't know if it's correct. Also when writting it I didn't know if i should use 바꾸다 instead)
3.- ____ without ______ ( like, for example: I would like a burger without onion)
4. And just to rectify if i want something extra I can say _____ 추가.
Thank you for your help.
