I know Coffee Bean has one CY store in La Brea in LA (it's also closed on Shabbos) but even there it really is just the milk that is CY, the whipped cream, mixes everything else is Stam. That's a different story and already CB already only has kosher food and like I said this one is closed on Shabbos so a lot of Yeshivish people that keep CY do go buy stuff there but I don't think Lubavitchers did (maybe some of you guys know).
