Fans of the late lamented Alex Bar B Q on Broadway in Williamsburg can take heart in Chicken "Q"-which serves an almost identical menu just across the street, on Broadway just east of Rodney Street. The rolled pernil, the morcilla, the cuajito-it's all there and its real fine. The place also sells CD's by Ramito, the Robert Johnson of the cuatro, and has a nice Boriquen vibe.
There is a sign that claims they make lechon on the weekends starting in March, and there is a painting of a guy slicing a pig on a rotisserie stake in the window, but I didn't see any lechon.
The place rocks!
