I saw some fresh black truffles last week at the Central Market on Coit near the Plano/Richardson border. They were in the produce section, and they weren't cheap. You might want to call ahead. If you don't need them this instant, you could try online somewhere.

Ate there tonight. The razor clams and yellowfin collar were both very good. Sally, who I assume is an owner, was a delight.

Fortunately it is located right around the corner, so I hope to visit again soon.
