I went last Wednesday, i split food from 3 spots with a friend so we could test it out. A few fried chicken bits from Chix, which was great. The sauces from them were also a highlight. Some detroit style pizza from Homies, and i think some fries/chips from somewhere else that i forget now. It was all of a pretty high standard, but it was also all total junk food.
You can order from most of the spots on Deliveroo/Just Eat/Uber Eats, so you could try before you venture out into the particle zone.
