Help With A Term In Katakana


I came across the following phrase and have been struggling to find what part
of it is meant to be in reference to:

> エルアディーナーの壁画

壁画 is obviously just for a fresco/painting but I've been unable to find what
エルアディーナー is meant to be. For full context it's about a coat at a fashion show,
and the full sentence reads:

> エルアディーナーの壁画をヒントに従来のコートをマキシム調に。。。




just doing a basic search: ディーナー means diner, taken from English. It's about a
restaurant called Elua (or whatever similar sounding word)
