Coffee & Food(No Beer) 

Hinkle's Restaurant - A Columbia landmark for  a century. It is where the locals go to eat.  Big portions, affordable. Right down from Rocky's BBQ and Columbia Kettleworks. Also has a store full of local  goods (Murphy's Mercantile).    

Prince Street Cafe - Columbia - Prince St Cafe now has a shop here in Columbia which is wonderful. Great coffee and food and a cool building to boot!
