Grill, grill, grill. That’s all chefs wanna do in the summer. And Brendan Pelley, executive chef of Zebra’s Bistro & Wine Bar, is no exception. He’s got a four-course evening planned for tonight at the Medfield New American restaurant. The evening promises to be relaxed and fun, and an opportunity for guests to chat with the chef. A sample of the menu includes grilled littleneck clams with a spicy grilled tomato ragu and grilled baguette; grilled scallion polenta; grilled skirt steak Thai-style; and grilled stone fruit for dessert (6:30 PM; $40 per person; space is limited; 508-359-4100; click here for more information).
