Ok, just got a text from her with some spots off the top of her head.
Here you go:
Hank's Seafood Restaurant (
http://hanksseafoodrestaurant.com/menu.cfm)
Indaco, Italian Food & Wine (
http://indacocharleston.com/)
82 Queen on Queen St. (sorry, website didn't open up here at work).
Those 3 are a bit high end, but great for a nice date night out. You know, if you're feeling that route!
Brown Dog Deli (
http://www.browndogdeli.com/). This is a very casual lunch spot, and you can get it to go and eat at the waterfront park.
Blind Tiger Pub (
http://www.blindtigercharleston.com/). Middle of the road price range, Irish pub feel, good burgers and stuff like that.
Mellow Mushroom for pizza (
http://mellowmushroom.com/store/charleston).
Poogan's Porch (
http://www.poogansporch.com/). Best shrimp and grits in Charleston, according to my sis.
These are going to be more affordable than the top 3 listed. Poogan's may still be more than the others, but well worth the trip.
Social Wine Bar (
http://www.socialwinebar.com)
Rooftop at Vendue Inn (
http://thevendue.com/restaurants/the-rooftop/)
Both of these are good happy hours (remember though, my sister is 27 so her happy hour may differ from ours. unless you're around that age as well.) Either way though, these are supposed to be nice spots.
Aaaaaaaannnnnnndddddd, cigar lounge:
Charlestowne Tobacco and Wine (

No website, so I figured the Trip Advisor link would work just as well.
Those were off the top of her head this afternoon, and she said she will work to get you some more spots to check out. She's also checking in with the more senior concierge's at her hotel (she's only been there a couple years) to see what they suggest.
Hope this helps!
