Hawksbill Diner is on East Main Street in Stanley, and it keeps breakfast-and-early-lunch hours: 6am to 2pm. It opens early and it closes at 2pm, so it works as the first stop of a day or as an early lunch — never as a dinner plan.
Two things are worth knowing before you go. It is cash only, so stop for cash first if you are not carrying any. And it is closed on Tuesdays — every other day of the week, Sunday and Monday included, runs on the same 6am–2pm schedule.
