I guess you'll get better answer pointing directly to Alexia Roux's portfolio. You'll probably note she used to different sans, one is own Alexia Roux's custom typeface called 'Perception' (as seen here) and the one you're after which I wasn't able to positively identify.

EDIT: after further inspection the second one could be Hurme Geometric No.2. At least I can't see any contradiction with it (/a, /0, /1, /2, /3, /5, /8, /G, /M, /L, /S...).
