Just my thought, and I know how you love to hear them!
I told you our experience at Boma was not great, therefore, I would opt for Boma at breakfast if I had to choose. Or you could do what we did Kona for breakfast and dinner! I know you want diff. places to take your ladies going on this vacation. Choose option 1.
While I haven't eaten there, everyone seems to RAVE over Kona's breakfast. Boma is our family's favorite place for dinner (my FIL talks about his meal there ALL the time). I even had some of the Boma recipes e-mailed to me!
I'm the pickiest eater I know, and I LOVED Boma for dinner. As such, I can't imagine recommending anything else. (Of course, I'd say if you're going to eat at the Poly, go O'Hana, but that's another topic for another day, eh?)
I suggest you read the breakfast and dinner menus for both restaurants and pick which breakfast and dinner sound best to you! You can also think, "Would I rather have a buffet in the morning or in the evening" This is how I would approach it, hope it helps!
I had both breakfast and dinner at Kona this past Nov., Breakfast was ok, dinner was not as good as other times I have visited. In fact, no one finished their dinner.
Boma has a GREAT breakfast buffet and dinner is okay but not greatif you have any picky eaters. Kona on the other hand is awesome for dinner and there dessert and awesome!!!!
