How to Develop this type of SiteBuilder Site?

Hi, does anybody knows what type of software or technology they used to develop http://www.letseat.at/?

I’m interested to build something similar for my customers but am totally clueless how and what they used to develop it.

Appreciate any advices.

Many thanks in advance.

There would be a lot of programming behind to scenes to set up a system like that. Not for the faint-hearted. What are your skills?

I know it needs a lot of programming and I’m not going to do it myself but I would like to find out more how they did it.

I thought I could tap on some of your expertise here that you may happen to know what software or technology they used to do it.

Any idea? Thank you.

I doubt there’s any way of telling unless they specify it themselves. There are lots of programming languages out there.
