My childhood friend from France is visiting NYC and he's a serious gourmand--he really loves food and will try anything (he's extreme--makes his own blood sausage kind of thing). We only have a couple of days but I want to take him to do some of those neat foodie things only NYC has to offer. One limitation is that we have to keep it to Manhattan, since our time is so limited and he's on a business trip. What I'm really hoping to take him to are neat NY institutions known for food, like the Sturgeon King on Amsterdam or the pickle shops in the LES. I haven't lived in NYC in a couple of years so I don't remember everything so I need some help! If anyone has some neat ideas please let me know. We only have a couple of nights and aren't on a huge budget, so if there are some really don't-miss reasonable (i.e. entree under $30-40 or so) places that are either super adventurous or just do what they do perfectly, please recommend away!
