Honestly, I don't think Hollywood Brown Derby is so much better than Mama Melrose's that it's worth giving up Boma for it. We've always had surprisingly good experiences at Brown Derby, and you're going to receive the same Fantasmic! seating either way. Boma is wonderful, and I suspect you'll really enjoy it.I'm staying at Pop but will have a car.
The menu at HBD is much more appealing but I do like the idea of a lazy morning and a DIY "brunch".
