Lunch and happy hour suggestions for Charleston, SC

I'm going to visit Charleston for the first time with my girlfriend. I'm planing to stay there for 3 nights in the beginning of December. I've done quite a bit of research and came up with a pretty decent food itinerary. I need some suggestions to fill our time there with Lunch and happy hour spots (we love oysters, so any place that has a great deal for them is much appreciated)

We get in Thursday evening.

Thursday Dinner: Cru Cafe (thinking of switching this to lunch if a better dinner option comes up)

Friday Lunch: ??
Friday Dinner: FIG

Saturday Lunch: ??
Saturday Dinner: Magnolias

Sunday Brunch: The Macintosh (should we do Husk, The Grocery, or High Cotton instead?)

So here are a couple of choices for lunch and feedback would be appreciated:

- Hominy Grill
- Husk (switch to Thursday dinner?)
- SNOB
- Two Boroughs Larder
- Butcher & Bee
- Xiao Bao Biscuit
- Eat at the Farmers Market on Sat Lunch?

Thanks in advance!
