Lucky you, it's a fantastic room. Either outfit would work there, tbh, and you certainly can't be overdressed when you've got giraffes wearing pearls around you.
If you remember, chance your luck beforehand at The Albion on Redchurch St, to pick up something for breakfast - they'll just have what's left at that time of night, but do v good sweet and savoury pastries, inc a cheese and Marmite whirl.
Also, little-known fact, the three boys live (or at least, used to live) above the restaurant, and share a huge wide bed made for three!
