Thanks for the reply Greenish, and you are right!!
Nothing in DFC open, but Madeleines in the Intercon was absolutely fab, busy with a great atmosphere, we had a lovely lunch!
I'm not there this year but since no-one else has replied yet, nothing within DFC was open through Ramadan last year. You could call the conceirge desk to check.
Bistro Madeleine in the Intercon is probably open.
