다면 알리다

let me know if you have

-다면 is a softer, more hypothetical "if" than -(으)면, and almost every line here is the same closing request to viewers: 있다면 알려주세요. What is being asked for changes — a recommendation (추천해주시고 싶은 또 다른 패스트 푸드점이 있다면 알려주세요), a tip (시간 관리를 더 잘하는 팁이 있다면 알려주세요), a routine, a home remedy for a cold. 알리다 practically always appears as 알려주다 here, with the -주다 marking it as a favour to the speaker.
