PERSONALLY, if I received a GC from a chain restaurant, I'd be a little offended, unless of course that I absolutley ADORED that resturant. You can buy chain resturant GC at the checkout line at your grocery store.....
My parents are in Delray Beach (east coast), they have local resturants with local flair up the ying yang. I can't imagine that Sarasota is any different.
OP, my suggestion is to strike up a conversation with the IL's guide it toward dining and see what places they favor.
Sometime the "older folk" do not like to try something new - they just like what they like.
