Wayland Town Crier 2/26/10: Olé for new Mexican restaurant!. Olé! Viva Mexican Grill and Tequileria has arrived in Wayland. And this is certainly not your grandmother’s burrito bar. The minute you enter the establishment, the second one opened by restaurateur Carlos Mendez (the first is the award-winning Jose’s on Sherman Street in Cambridge), you get the impression of sleek sophistication, warm and glowing colors, and excellent hospitality. After passing the bar area on the left, where bartender Gilad Avital (Mendez’ second cousin by marriage) whips up Viva’s signature margaritas and other cocktails, you will enter a large dining room. The menu is extensive, ranging from starters, salads, soups and casual fare, to traditional Mexican selections and specialties from the grill. And, yes, there are burritos, enchiladas, quesadillas and tacos. But there is also fresh fish, lamb, chicken breast, and slow-cooked pork loin. According to Mendez, his restaurant features authentic homemade central Mexican cuisine in the atmosphere of a Mexican country estate.
