Does any one know the office rule by Hyatt regarding breakfast in the restaurant?

Will be running the Sydney Half Marathon on 19th May, my race will start around 7:30, restaurant open 6am - 11am on a Sunday. Planed to go at 6 and grab my light breakfast, finishes race around 9:30, head back, have a shower and sure will be hungary enough to go for a big meal after the run.

I used to have two breakfasts at lounge which according to lounge access rule it would be fine for sure. However with Prive rate booking, I would like if me and my friend (both running), would be able to have breakfast twice in the same morning at the restaurant.

Thank.
