Hi - either a laminate print made to look like stone, or a natural stone such as granite. I expect your reclaimed wood cabinets have maintained a somewhat rustic look, so that's what I am basing my answer on. Liz from Cabpro Cabinets www.cabprocabinets.com

You could also do a combination of the above with some stainless steel. Concrete countertops are fabulous. So many things you can do with concrete now.
