I went to a Meet and Greet there a long time ago, and was impressed by it.   They have a nice bar area as well as a very good restaurant.

It's on Sahara just east of the freeway, just before the Palace Station.

Here's their website:

Dive bar or nice cocktails? Pub for a beer or a wine bar?
I like Herbs N Rye for a good cocktail. What time do you want to go? Some places don't get going till late, others have a good happy hour.  The Firefly is popular... not my scene, but very popular.
