Map of Soho Good Omens Season 2 - Part 1 (Location and general map)
Part 2 | Part 3 | Part 4 I think we all have wondered how the GO Soho looks like and where it would be in real London. So using all the screenshots, BTS pictures and videos I could find I did my best to map out where things are. It is not to scale but everything I could see is there. I originally had all the pictures and explanations in this post but soon it became obvious it was going to be too long and impractical so I had to split it in different posts and I hope I got it right. The map has five reference points (circle with two diverging lines); imagine the circle is you, standing in the set, and the lines are your viewpoint if you were taking a picture from there. The left side of Whickber Street (#1 and #2) is in Part 2, the intersecting street (#3 and #4) is in Part 3 and the right half of Whickber Street (#5) is in Part 4.
As to where the bookshop would be in real London. We know that Whickber Street is supposed to be Berwick Street so let's start there. The intersecting street is not obvious from the show. In this post Neil said he imagines the bookshop to be where Gosh! Comics is (Peter Street) while Michael Ralph and Douglas McKinnon probably put it at The Week (on Broadwick Street). Because it is ambiguous and really you can do whatever you want, I just left it as "intersecting street". We know from the book that Crowley takes Wardour Street after the bookshop fire. Wardour is behind Berwick so in our map it would be where the Chinese Buffet Restaurant is, considering they run more or less parallel. On the other side, we have the Windmill Theatre located on Great Windmill Street. From Berwick St. and Peter St. it takes three minutes to walk to the theatre, it is that close! (yes, I know, Crowley was conducting business two blocks from the bookshop while not talking to Aziraphale for 80 years). I have never been in that part of London so I used Google Maps streetview and based only on that, I like the corner of Berwick St. and Broadwick St. better. It has the crooked intersection but the proximity of the theatre matches Peter St. better, so whatever works better for you!
There is one place missing from the set map though: Brown's World of Carpets! It is nowhere to be found, we simply don't know where it is My very personal headcanon is that it is nothing but a desk inside the furniture store. I find that idea very amusing, but don't mind me, it is just my very silly hc XD Now, we know Aziraphale has a list for the shops he needs to visit. And we know he wrote it in alphabetical order which begs the question: Where is the Dirty Donkey?! Are they not invited? And what about the fabric shop? And Bilton Scaggs? Battye and Palm? The News Agency? and what is up with this "Lucky Snake"? no storefront actually has that name! Is "Mo Coffee? No Coffee?" supposed to be Give Me Coffee or Give Me Death? Or is there another coffee shop somewhere? So many questions to ask Mr. Brown.
