Cali Grill is our favorite place @ WDW. We vowed to end each trip with dinner there. It's simply amazing!! The pork tenderloin with goat cheese polenta is TDF, and the sushi is amazing too! You can't request a table by the window when making an ADR (so I was told by the CM), but you can when checking in. They will tell you that it may add additional wait time - and it's your choice to wait or take the first table that's ready for your party size. When your buzzer goes off you can ask where your table is located, if it's too far from a window you can just wait. You can sit at the bar and have a drink, or just relax. We always do that. Our first trip we waited for a window table, this past trip we took the first table that was ready and still had an amazing castle view. Time it with Wishes and go out on the balcony for a wonderful, romantic view!!!
Another really romantic place that DH and I love is Narcoossee's - it's delish, on the water, and has killer views of Cinderella's Castle too! You can time it with the electric water pageant which is really cool too!!
