I think Tony's Town Square in MK can be, of course no alcohol in MK. I also think Coral Reef could be too.
Then of course you have your standard steak house 2 table credit meals. We celebated our 35th anni at Spirit of Aloha, might not seem romantic to some, but then I did not walk down the isle to the traditional wedding march, but to Andy Williams singing Hawiaiian wedding song, so for us it meant much. I think any restaurant can be romantic, it is the person you are with who makes the romance.
We also very much enjoyed Le Cellier during that visit too.
Congrats.
