Try El chalan in Eastie for Peruvian style chicken. I liked it- though I admit it didn’t rock my world.
The chicken was by far the star- I always got it with plantains which always were wicked dry but who cares about sides when you’ve got roasted chicken?
Also it may be worth noting that I’ve not ever had the genuine article so I’ve got nothing to compare it to, not even two other local places that do it-Beto’s or Machu Pichu in Somerville.
I seem to recall another place in Eastie that was once raved about on chowhound though the name escapes me now (and I think it may have been Mexican).
El Chalan is at 405 Chelsea St in Eastie.
Beto’s: 69 Bennington St in Eastie.
Macchu Picchu: 25 Union Sq. in Somerville
Good luck hunting and feasting.
