I agree with Uncleromulus here on Citrico's, always been one of our favorite restaurants for good food and good service, but as far as being romantic, I would say it was more bustling and lighted well...
I have eaten at both California Grill and Jiko's and still like Citrico's better for the food and service. I also like Bistro de Paris and when we ate there back in March we saw a couple at the next table and he was proposing on his knee, ring and everything, it was so nice...I guess he thought it was romantic enough to do there and we found the service good and food good as well.
