À la recherche de petit dejeuner perdue
My what a hungry bunch you all are

There were some breakfasts that were about memories and views. Nice to hear those memories.
A breif but intense re-entry to the topic of the Full English/Scottish/American breakfast and the nature of bacon
Loco Moco and Bahn mi were new to me so I'll make sure to try those if I get a chance.
On the topic of Turkish breakfasts, the Armada Hotel in Istanbul has a massive breakfast spread on the roof. I got a smattering of everything but then I went to get some tea and returned to chaos. A couple of giggling Japanese ladies said "The bird got it" presumably refering to the seagull that had been showing some earlier curiosity.
For quick breakfasts I like Tim Ho Wan dim sum. Many people mentioned dim sum. There could probably be a productive thread on just that topic.
Not too many name drops on fancy restaurants. I am more than happy to spend a couple of hours having breakfast if need be. I think all three of the ones I mentioned took well over an hour to get through.
Breakfast is not something to deliver like Haute Cuisine I agree, but caviar would be on a lot of my ideal breakfast menus and a lot of the breakfasts at those fine London hotels excel not because they are fancy but because they have chosen the best sausages money can buy.
I can't remember who mentioned it above, but having a proper steak and eggs for breakfast is probably the best US option I have come across. Only trouble is it doesn't really go with my two favourite breakfast drinks Champagne or Bloody Mary, it goes best with beer and I don't really fancy beer in the morning.
