Start with Aura Cafe and Quinta Gameros
Use one real cafe and one real sight.
- Start at the cafe
- Move to the sight
- keep the next stops close enough to make sense
Start the day with Aura Cafe at Paseo Central 3218, Chihuahua, Chihuahua, Mexico, then move to Quinta Gameros at Paseo Bolivar 401, Centro, Chihuahua, Chihuahua, Mexico.
That gives Chihuahua a route you can actually explain without falling back on generic district talk.
If you still want one extra stop, use La Casona or Plaza de Armas only if it stays on the same side of town.
