One requirement for calling yourself a true New Yorker is having a favorite neighborhood diner. If you live on the Upper West Side, then your answer is easy - Viand Cafe. Like at its Upper East Side location, the menu here is huge, ranging from omelettes to meatloaf, but the most important thing to know is that they roast their turkeys in-house. Which means you should be ordering their turkey sandwich. The big booths and midnight closing time also make it a good option if you want to eat some pancakes for your second dinner.
