I drove by again on Friday and discovered that the 24-hour restaurant was open!
Then, I spotted on the Corky’s website that a fourth Inland Empire location is planned for Corona, at 3811 Bedford Canyon Road, Suites A8-A11.
The Eastvale Corky’s, which joins locations in Rialto and Rancho Cucamonga, is at 12552 Limonite Ave, Suite 130.
There’s also a non-I.E. location in Ladera Ranch.
