The Burnt City
STPD has been 8 times at least - people seem to make repeated visits as you can't get the most out of it on a single trip.
Basically you walk into the middle of a play and follow the action, which takes place in multiple rooms and sets inside the warehouses, and the action takes place around you. Many things are going on at the same time, so you will only see a fraction of what's going on at any one time.
The whole thing loops around and you get three loops in your visit.
The story is the Invasion of Troy and begins in Mycaenae with Agamemnon's sacrifice of his daughter Iphigenia to bring good luck for the invasion. FINDING Mycaenae is apparently tricky, as is finding Troy if you happen to start at the Mycaenae end, but things are going on in every room and every space so there won't be time to get bored

I have a few goals for myself on this first visit - I want to see the Watchman in Mycaenae (he gives out packets of seeds to a lucky few - STPD got some once!) - find the Flower Shop in Troy (apparently it smells of 'rose jam') - visit the Sake Bar and encounter Zagreus - and get to see HADES! Hades lives in a big house in Troy and is apparently quite the charismatic character - if you are lucky he might beckon you in, lock the doors and involve you in a special secret scene!
I have no idea how this is all going to go but I am SO excited! I have been following the whole thing via STPD's visits and began to long to go myself.
We are going to the evening performance on Sunday night, staying at the Premier Inn, Woolwich (!) and home on Monday morning. Repeat visits already booked for April and May!
