So for the last four or five days of the egg hunt, most of the eggs were in Covent Garden - not all of them, and not all on display - some were just being stored. I went round a couple of times and took photos, so here are the ones I got:
These ones were in shop windows; apologies for the reflections, there was nothing I could do about it.
Final zone!
Eggs in this zone: 45
Eggs I found: 30
The eggs all ended up at Covent Garden for the last few days of the hunt, so I'll be posting a wrap-up post with the ones I didn't manage to find (not all of them - there are a few I have seen pictures of that I couldn't find myself).
