Need help,....Looking for gift ideas for some senior friends...

I have a birthday to go to this weekend. The birthday boy just turned 83. He's wife turned 78 last month.
I wanted to get them Gift Cards from Carrefour so they could get what ever they wanted but Carrefour no longer sells them.
Does anybody know if there's a big department store here that has them?. They're well educated world travelers.
Both architects, I know them because they were friends with my parents.
Walmart ? Farabella ? Sube ? Carrefour ? jeez, what about some great bottles of wine or a fabulous restaurant, you know a splurge!
