OOOO.K. - have done some research.
Thing is, you only need to now which people to ask.
And for that in Hamburg there's nothing better than the St.Pauli Fanforum - they've never failed giving me the information I needed.
What Toytown is in Munich, that's
St. Pauli fans in Hamburg - just more of them
After only 2 hours they came up with:
Die Kogge - Rock'n'Roll Hotel und Hafenbar. A girl from the Fanclub Arschrock which I know (and she and her bf usually know all the good places in St. Pauli) has recommended that.
Recommended by 2 people:
Bar Centrale at Clemens-Schultz-Str. 66 in St. Pauli (there's also one in Gertigstraße, but not with English breakfast I guess).
Called them for confirmation: they have full English breakfast on Sundays from 11 a.m. - cooked by an Englishman!
Café September opposite to Heiligengeistfeld - Schanzenviertel/St.Pauli - have something for breakfast called "very British":
QUOTE
7) Very British
Baked Beans mit Tomatensauce, 2 Spiegeleier, Bacon, Bratwürstchen, Senf, Ketchup, dazu Toast und Orangenmarmelade EURO 7,20
The German/English speaking Stammtisch took place there a few times - maybe somebody tasted this breakfast??
Also mentioned but possibly not an up-to-date info:
Fritz Bauch Szenekneipe at Schanzenviertel served English Breakfast two years ago - don't know if they still do.
Have not been to any of these for breakfast, but maybe you wanna give it a try - and let us know how it was

The "Kogge" seemed pretty cool to me. And Bar Centrale is also a sportsbar, have heard good things about it before.
