never set foot in (some place)
To never enter or travel to some location. Can be used as an order or a statement of intention. The preposition "in" is dropped if the pronouns "here" or "there" are used. It wasn't me—I've never set foot in that building before! After the awful time we had in that restaurant, I'm never setting foot there again. I told you, never set foot in my house again, or I'll have you arrested!
