We all know that artist Jasper Johns came up with the name Abacus for Kent Rathbun’s restaurant right? True story. Maybe that explains how Rathbun came up with Jasper’s for his backyard gourmet spot. Anywhoo, now comes word that arty people work at Abacus: Pastry chef Rick Griggs and server Tamara White are both successful artists. Their original works will be featured at the upstairs gallery of Nest in Snider Plaza. Opening reception on Thursday, May 7 from 7:00 pm to 9:00 pm. 214-373-4444.
