The aroma of hot chili peppers and onions is in the air at Tacos El Norte. Tucked away in the corner of a strip mall off the west side of Route 12, this restaurant features Mexican cuisine against a backdrop of colorful murals. Owner Peter Knopfhart has been running the place since 1995. Dine-in, carry-out and catering are available. The menu is expansive, including breakfast (served all day), appetizers, salads, house specials, soups, a children's menu and homemade flan.
