Via Lago is right in Lexington Center, with a great menu selection for either sit down (order deli style, then they bring to your table) or take out. I love hitting this spot for lunch. Great daily specials, pressed sandwhiches, big selection of pasta salads, quiches and hot meals. It's popular, so often there's a line. But the serivice is quick and the food is quality so it can worth the extra few minute wait.
Pros: Great selection, quality food, reasonable prices
Cons: Long lines, parking can be tough
