You know what they say: Lamb is the new beef. Okay, perhaps that saying hasn’t quite caught on yet, but one bite of the burger at Clock Tower Grill and soon you’ll swear by it. Made with grass-fed lamb that restaurateurs Cassie and Rich Parente raise on their very own farm, the burger consists of ground shoulder and hind cuts, topped with tandoori yogurt sauce — a mix of local yogurt and red curry for a little extra zing.
