I visited Westworld of Scottsdale for their 4th of July event last week. I must say that this place is pretty big and can accommodate a good number of people. The catering was ok, but it lacked some good tasting food/dessert. What I didn't like about the place was that the main building smelled like horse urine. I understand they probably hold a lot of rodeo events, but they could have cleaned that up a little better for this event. I didn't even want to hang out inside the building for that reason. I also wasn't a fan of the swamp coolers that they had cooling the big building. It was a little muggy during the hottest part of the day. I can see why they don't host the Bird's Nest there anymore.
