Visiting Hubby's hometown, first time since 2011 & also friends from UK getting married

Hello! My hubby is a Vegas native, but we haven't really been back (and his family moved away) since our wedding in 2011. We are staying off strip in an Airbnb, but he kind of wants to have the quintessential Vegas experience. On top of that, my British friends have spontaneously decided to come out and get married during our trip. We want to make sure they have a wedding day to remember. Their wedding is at 12:30pm at the Chapel of the Flowers, and it's likely we will be the only guests. Where could we take them after, which would be fun, memorable, and make them feel special. We have a mid budget, although good deals never go amiss! Dinner, drinks, a show? Or are there some quirky ideals I won't have thought of? Thank you!
