Jimmy invites Emily, Kathleen, and me to a "soft opening" for Black Pearl, his friend's cool new fish-fry in the Flatiron District. A soft opening is a sort of pre-opening only for friends, family, family of friends, friends of family, friends of friends, etc. etc.

Save room for the key-lime pie, which is so good, I wish I was eating it right now.

Is there an expression one uses to properly wish somebody good luck on a restaurant opening, something along the lines of "merde" or "break a leg"? Harold suggested "break an egg", which is ridiculous.
