I hate that there is one generic category for" Latin American", and that some Mexican places are lumped in despite there being a Mexican category. Anyway, it was difficult because of this category being lumped together, but in the end I give it to Mach Picchu. Here, you can eat healthy or indulge, cheap eats or elegant multi courses. Ceviche, causal limena, papas rellenas, chicharrones, arroz chaufa, I could go on all day. And the cocktails! Pisco Sour is the national cocktail of Peru and they make it wonderfully here. Despite it not being a Cuban/Puerto Rican place, they make the very best traditional mojito in the Boston... and believe me, I know...I test them out everywhere!
