Inspecting the website with the Whatfont app the embedded font is called »gallerirobust«. So I assume it is a custom one.

Houschka by Nick Cooke would be similar (and it comes without those annoying slab details)

Designed by Kontrapunkt. Renko's call of Houschka would surely provide a good base font, probably the closest one (/M to be tweaked). Mixing Museo and Museo Sans plus some little tweaking could work as well. Proxima Nova even if top rounded /A needs to be reconstructed would be another option.

Thanks for your help guys :)
