Tusker House for Breakfast was our favorite of 6 character breakfasts we did on our last trip. For what its worth, I'm picky, hate onions (don't remember all the dishes with onions in them) and there was tons of stuff for me to eat. You have all your traditional American breakfast foods, and there are some "African" flavor type foods as well. I've never tried Boma, but Tusker House is number 1 in my family's book!!
Have fun!
