Nick's. I love Nick's Restaurant. Let me preface by saying I haven't actually had anything to eat there.
I like stopping in to get a drink before a show at the Overture. It is right across the street, and the bartender guy is always very friendly. It feels like a classic old-time diner, minus the cloud of smoke I would get in mountain country bars back in day (living out west).
I like being able to stop in, have a drink, and inconspicuously head on into the night.
