I would highly recommend Top Golf Las Vegas for an evening out with a big group of friends. Go at night (although its a high rate per hour to play in the evening peak hours) I think its worth it with the view. People of all levels and people who have never played golf before can play. If they are super anti golf they can find fun at the pool, or other games that top golf has.
Attire is kinda weird at top golf - depending on the time that you go some people get really dressy in the evening and some people look like they are going to a night club others are super casual. But there is no dress code that I am aware of so just wear what you want.
Also the food and drinks are pretty darn good! They have a drink that comes in a golf bag shaped drink glass that lights up. ITS REALLY COOL and all your friends will be jealous !!
Pro tip- You can bring your own clubs if you don't want to use the callaway clubs that they have and if you have time, remember to bring your golf glove !
