I just MLBed my Chaldea Lunchtime and was wondering where the best location to farm bond is. I know the previous location was In Fuyuki but my quick math tells me that it's not as efficient with Lunchtime.
Double mlb chaldea lunchtime on the 40 ap hunting quests gives you over 1000 bp.
Singularity and event main quests usually have better bp levels than free quests or dailies.
Just keep lunchtime equipped as often as possible and don't worry about farming bp specifically, it will happen naturally.
Camelot nodes has great Bonds reward, particularly Mirage of Dreams quest in Hidden Village
They give you 795 raw bond points, so if you bring 2 MLB Lunchtime and a Heroic Portrait (+50 Bond point) you'll get roughly 1k BP per 21 AP which is nice, also the node has only 2 waves with Caster boss so you can easily farm it using good Riders. (thi rist wave has 2 assassins but that won't matter too much since you'll probably using waver support with lunchtime)
^this
but if you are looking for just the highest amount of bond per run then you can do Royal Castle in Camelot instead. It'll will give you 20 more bond for the same AP but it is 3 waves of strong sabers so it's harder/takes longer
