Can I get a Chicken Sandwich around 9am or do I have to wait until 11am or noon for lunch to start?

Yes you can. There menu is served all day except for breakfast. I have gotten a combo meal before 11. So yes.

According to the website, breakfast is stopped at 10:30am and lunch starts being served at 10:30am. So, I would say no chicken sandwich until after 10:30am.

I think you can
