Delivery options in downtown Charleston?
I've been living in downtown Charleston for about a year now, and still have found few dinner delivery options. Outside of the standard Pizza Hut etc., I've used a few Chinese restaurants and D'Allesandro's Pizza.
Is there anything else?
A few of the sandwich places deliver too. I like Bubba Slye's on upper King. Mellow Mushroom is the best delivery pizza downtown, but their prices are steep even before delivery charge + tip. Aroma's on Market will deliver, they've got solid but unspectacular pad thai. Pita Pit delivers if you're looking for a quick lunch. Easy Bay Deli does too.
That's all I can come up with off the top of my head, hope it helps.
