I'd second Kona for breakfast or a to-get-out-of-the-sun lunch - we had an unplanned late lunch there last trip which was nice. But for dinner, it's the kind of place you go to when you don't have reservations anywhere else, you won't be disappointed in the meal, but there's not much ambiance, not much of a view. I'd say the same things about The Wave at the Contemporary & Turf Grill at Saratoga, all nice restaurants with tasty options I still wouldn't necessarily go out of my way to visit. Were I the OP, I'd choose Cali Grill and then have a breakfast or lunch at Kona. Lots of people don't think about it for lunch, but it's a nice option when you're visiting the MK. At lunchtime, instead of fighting the crowds at a counter service place in the park, or the noise at a sitdown restaurant in the park, monorail over to the Poly, get out of the sun, you'll really enjoy the meal, and feel recharged to back to the park (at least when they're not under renovations).
