Gordon Biersch does not need any more positive press. They are as crowded as can be during Happy Hour and when they have their tapping parties...both of which are good.
GB is an above average bar with an above average restaurant. They have one of the better patios in the westside/summerlin areas.
Their beer is okay. I am a fan of the Marzen and their winter seasonal, the Winterbock.
The wait staff does a real good job and the managers are great at this location.
That being said GB is too popular/crowded for me, and doesn't offer quite enough quality beers on a regular basis for me to come here more.
