I would have to say our favorite has been Fresh Mediterranean Market at the Dolphin. There you CAN get your made-to-order omelets, and unless they've changed since we were there, you can even select your own ingredients and hand to the chef. The juice extracts were also something that is above the "norm". Just a superior quality all around.
There is a separate menu there as well. Much cozier atmosphere.
The one thing - it's at the Dolphin - so no dining plan.
