Adare Farm Ice Cream Cart

As the guests left the church, quite parched, and after sitting in a church for an hour; they were met by an ice-cream cart! They are still talking about it, 2 years on.
It's a little weather restrictive. They can set-up in the hotel if its a wash out. If the weather is any way decent (our day wasn't particularly warm, but it didn't rain), you're on to a winner here.
You can choose the icecream colours to match the wedding colours.

If you can work it into the budget, this little extra can add a lot to a wedding.
