I am just mentioning places that are currently open. Outside the parks - California Grill and Narcoossee's can be romantic. We also like the Enchanted Rose Lounge, which has a light bar menu, and the Three Rivers Lounge which has a more substantial menu. Inside the parks - San Angel Inn, Coral Reef, Spice Road Table, Nomad Lounge and Tiffins all have potential. Sci-Fi is more cartoony than romantic, but it is dark and you are in a car. ;-) I do not find Cinderella's romantic, but many people get engaged there, so obviously some people do.
