Retaurant Misti on N. Main Street in Port Chester is one of that village's half dozen or so Peruvian restaurants. Their strength is their pollo a la brasa (rotisserie chicken.)
When Misti is performing at its top level (and it does more often than not in my experience)its chicken is very good. My wife and I prefer Misti's chicken to Pio Pio's (based on one experience at the Nothern Blvd. branch of the latter.) I find Pio Pio's sauces better, but not enough better that I would pass up Misti's chicken. (My wife isn't a sauce person and, thus, doesn't even consider it a choice.) The chicken at Misti is herbaceous, with a cumin accent. It's a bit salty, but this seems to be universal with Peruvian pollo.
Misti has its occasional off nights when the chicken is below par (This appears to depend on whether the owner is in charge of the kitchen on a given night.) Their sides and other Peruvian dishes are no better than average. There is better elsewhere in Port Chester. Go for the pollo.
Misti is at 100 N. Main Street. Phone nuber (914) 939-9347. (For once I got a card and can actually find it when I need it.) It is two or three blocks north of the intersection of Main St. and Westchester Avenue, on the left when heading north. Don't confuse it with another pollos a la brasa place (El Festejo) a few doors further north. To my taste, El Festejo's chicken is inferior.
