BY SUSIE CURRIE — On January 28, The Wild Onion eatery became the latest vacancy at University Town Center, where it had been since July 9, 2008. Catering is still available, though; call owner Rasheed Abdurrahman at 240.476.5054. In other restaurant news, it seems that rumors of the death of Under the Coconut Tree, at 5124 Baltimore Avenue, have been greatly exaggerated. Fans of the Caribbean cuisine were anxious when the store closed for a few weeks last month, but it’s up and running again under new management.
