Edinburgh city centre - light lunch suggestions?

[Jumpingintosummer]

Looking for suggestions for a light lunch with good coffee in Edinburgh city centre. Meeting friends with kids during the week so would be 2 adults and 3 DC (9,10 and 15). All suggestions much appreciated.

Urban Angel on Hanover Street?

My favourite @Rachie20, booked in for brunch the day before.

Going through for one night for catch ups so having brunch with one set of friends at Urban Angel on Thursday morning, dinner at Kyloe Thursday night then need somewhere for lunch Friday with my other friend and DC’s.

Laila’s on Mary King Close? Other places I can think of are further out or are more lunch-y than brunch-y.

There is a cafe in the church at the western end of Princes Street, cannot remember the name, but I have gone there on several occasions when in Edinburgh for the Fringe.

Lunch-y is ok if more sandwiches etc than sit down meal?

Will google the church suggestion and look for a name. Anywhere top of leith walk/holyrood direction good as planning to go a walk afterwards.
Thanks for the suggestions so far.
