We opted against pre-ordering last month, simply because we had no idea 30 days out (or even a few days out) what we might be wanting that morning. Ordered when we got there and still got our food pretty quickly. We had ten people in our group, so I am relatively certain that we ended up with several things on the main menu -- cronut (awesome), open face bacon/brie/egg sandwich (that was mine -- also quite good), the eggs Florentine in the pastry shell and the veggie quiche (didn't try either, but both got good reviews from those who did), and, what turned out to be the favorite, the relatively new breakfast item -- croque madame. Pretty sure that one was not on the original breakfast offerings, but when we saw it a couple of days in advance, we knew we would end up with at least one among our own little family foursome. It was probably the favorite of everything.
The $19.99 price seems a little high for breakfast, but considering it includes a drink (with unlimited do-it-yourself refills), the pastry platter (which comes with everything) and then the actual entrée, I felt like it was a relatively good deal.
