The Renaissance Tampa Hotel International Plaza restaurant has an exceptional everyday breakast buffet.
Maybe the finest Sunday morning breakfast buffet I've ever seen anywhere is at the Renaissance Vinoy. An exquisite buffet in beautiful surroundings.
The Marriott Louisville Downtown concierge lounge buffet actually has (my heart be still), scrambled eggs, bacon, sausage, and smoked salmon.
The worst breakfast offering: the concierge lounge at the Milwaukee Marriott West; slim pickings indeed, unless you want oatmeal every morning.
