There are a large number of good restaurants in close proximity to Vanderbilt. Maybe it has something to do with the zoning of the city, but it seems like Vanderbilt lies in a very highly concentrated restaurant area of Nashville. In every style and price range, you will find something within walking distance or a short cab ride.
The selection certainly exists in the city; it is only a question of the depth. There aren't dozens of excellent places to eat for every genre of food, but excellent places do exist. This means that it is very important to make reservations, or you will find yourself standing in line holding one of those silly pagers.
