Looking for advice regarding my friend’s London Bucket List.

My partner and I have only just moved to London so we’re not the most savvy on where to go. We have some friends coming to London as part of their Honeymoon and they have a very specific bucket list they’d like to complete while they’re here. I’d love some advice on the best way to go about it as well as general tips when visiting these spots since some of the things on their list are extremely vague and I’d like to make to most out of them. They’re very Instagram type people and would love some very photogenic locations if possible, whether it be the food or the scenery!

List:

A red phone booth (yes they’re serious) - Which areas have a good view of the city where they can take cute pictures, rather than just showing them any telephone booth?

3/4 Platform Kings Cross Station (if time)

Waterstone's (the largest one in Europe)

Fish & Chips - they specifically want to go to a more historic location or just a generally very old Fish and Chip shop

Meat Pies - Best ones you can recommend in terms of taste and/or look

Traditional English Breakfast - They said they don’t want to go to Gregg’s so what are some other essential places to get a proper Full English Breakfast (not a Sunday Roast)

A Pub - I informed them we can go on a pub crawl or Spoons to get a better idea of normal London places but they definitely want more touristy options, whether they be older or just cozier.

Thank you in advance, would also appreciate any general recommendations for where we can take them.
