I like to try a place a few times before posting, but Machu Picchu expanded into a big space across the street at exactly the wrong time and they could use the business. The big-dig style Somerville Ave construction is hurting all of the businesses in Union Square and MP is no exception. I wasn't BOWLED OVER by the ceviche or the aji de gallina when I've visited before but the family did maintain their little storefront right in the tip of the building in the heart of the Square, and they opened a "pollos a la brasa" place. This is rotisserie chicken Peruvian style. It is scrumptious.
$8.99 gets you half a chicken, fries and a salad. I skipped the fries and the salad was as you'd imagine -- iceberg, a few cukes, a sweet creamy dressing. But the chicken is great -- moist and juicy, rubbed with Peruvian spices they import and cooked on a spit like they do back home.
The little room has been redone, with a pretty little bar and colorful walls. They have a liquor license which is all too rare in the 'Ville ie: they can make you a Pisco sour. Yes, the road-work and traffic are not nice, but I found a metered spot on the first try. Anyway, do check it out. I think this will be a perfect place to pick up dinner on a hot summer night.
