It was obviously a word-processing typo. The description in the menu for the Lamb Vindaloo was identical to the description for the Chicken Vindaloo: "Mildly spiced chicken ... in a hot sauce"
I had followed the recommendation of the VND's Lunch Bunch who recently reviewed the new Zaiaka Indian Restaurant.
So when the typo in the menu was pointed out to me I had to ask the waitress, "How much chicken is there in the Lamb Vindaloo?"
She struggled for a moment with how to answer the question, then gesturing with her fingers explained that it was cut into pieces about so big and that there were maybe eight of them in a serving.
I asked again, "How much CHICKEN is there really in the LAMB Vindaloo?"
She finally figured out what I was asking and acknowledged that the chicken was in the chicken vindaloo.
The Lamb Vindaloo was rather spicy, as promised. and it was completely free of free-range chicken.
