In last week’s Dine 909 column, I mentioned that long-time Highland restaurant Roberto’s Pizza and Italian Dining, 3669 Highland Ave., is “closed until further notice.” A reader had emailed us of the closure.

Following up on another email, from reader Shawn, I went by the Iron Chef Cafe, 4275 E. Concours Drive., #30, Ontario, this week to discover it too, has closed.

The reader noted that they began a “kitchen remodel” back in October and never re-opened.

A red do-not-enter sign was displayed in the front door.

The Chinese/Japanese restaurant opened at the end of 2008.
