Winburg is the oldest proclaimed town (1837) in the Orange Free State. As the N1 bypasses this small mixed farming town, do not expect 24-hour service here. It would be advisable to phone ahead during the daytime while you enroute to place food or accommodation orders/bookings. Food may be good, but not necessarily fast.
CAUTION: Winburg is one of those typical Free state daytime, weekday trade towns.
