There is no list, because reservations are needed for almost any restaurant that you're sure you want to eat at.
There are some lesser known restaurants that you may have luck getting into on any given night, but even then if you know you want to eat at a certain place at a certain time - reservations are a necessary evil.
There are a few that don't take reservations (Beaches and Cream ESPN Zone come to mind), but they can be challenging to just walk into at a prime dining time.
