McHenry's newest restaurant has pushed back its open date, the owners said Friday. Jexal's Wing-Zeria plans to open next week but not on Monday as previously stated, co-owner Mike Dumelle said. The restaurant plans to hold training for its employees Friday and Saturday, Dumelle said. On Sunday, the restaurant will remain closed. "We will be closed to recap with our team, let them rest a bit, and based on feedback and such, we as a team will determine and post the exact opening day next week," Dumelle said. Delivery service won't begin until January, he said. The casual eatery had originally planned a tentative open date of Dec.
