Toddler friendly restaurant near Horizon 22

[24HoursFromTulseHill]

I've just booked tickets to take DS (3) to Horizon 22 and need a plan for lunch nearby afterwards.
We like places with quick service and easy to fit in a buggy without having to empty & fold it up. Bonus if I can pay the bill online or upfront so no hanging around afterwards.
Wagamamas and Whetherspoons have been a hit so far.
Does anyone have any recommendations?
It's on a Saturday so should be quiet in that part of the City.

Have a look at paradise green.

No kids menu but they will adapt stuff. Pretty relaxed and space for prams.

There are two Wetherspoon pubs along bishopsgate the Crosse Keys - pretty much opposite and Hamilton Hall(next to Liverpool Street station. Have a super day.

Also, check out what’s in Leadenhall Street Market, I’m sure there’s a pizza express or something similar.

Thanks for those suggestions - I'll check them out.
Hoping to do a trip on the DLR afterwards so it should be a good day.
