There couldn't be a more perfect spot to watch the day's events unfolding than Galvin at Windows. Watch the wedding reception unfold at Buckingham Palace from the plate glass windows overlooking the Queen's garden - plus you're perfectly placed to see the RAF flypast just after 1.30pm.

Having spent the morning braving the crowds down the Mall, hoping to catch a glimpse of the couple as the coach takes them back to Buckingham Palace once the deed is done, you're probably not going to want to walk far.

What to order: Duchy of Cornwall native oysters of course.
The restaurant where you can eat like royalty
Pierre Koffmann's Berkeley Hotel restaurant is where Camilla took Kate Middleton for a ladies' lunch to go over what she can expect from marrying into the royal family.
What to order: If you'd like to do the freaky royal stalker thing, happily The Daily Mail found out, allegedly, the exact food Kate ordered: so go for the terrine of foie gras with baguette, followed by sea bass with fennel and black olive sauce and Koffmann's famous pistachio souffle with ice cream for dessert.
