Here are a few suggestions of spots around Philadelphia that we've found to be romantic, along with ideas from our Twitter and Facebook friends...
Bistro Romano's Wine Cellar Table - Headhouse Square's Italian staple holds a special place in our hearts. We ate here the night we got engaged and it couldn't have been a more romantic celebration. The dark-lit dining room with exposed brick walls and cozy wooden booths-for-two serves up classic Italian dishes that won't disappoint.
For an even more special evening, try to get the private wine cellar table. Rose petals and walls full of old wines create an intimate setting for the most romantic of meals. It has to be reserved (I can't guarantee it's free on Feb 14th) and costs $15 extra. Lombard Street between Front and 2nd.
