I ate at both these places last October. Captain's Grille is unique because there is both a menu and a buffet. I was all set to order off the menu, but my server encouraged me to go look at the buffet, and I did end up at the buffet after all. I was wanting eggs benedict, and they are on the buffet along with a yummy french toast bake thingy and great fixings for the oatmeal. I liked the fruit, too.
Kouzzina is unique, but I think they had a traditional breakfast, too. I had the orange/blueberry pancakes; they were huge but yummy and also with sausage. I couldn't finish them all.
I opened both places right at 7:30, so they were quiet and had great service. I cannot speak to how they are later in the day, though!
