What unique experiences does Sonia Justo recommend for visitors to Belém?

In Belém, loves experiences that mix history, views, and flavors:

1. Watching the sunset by the Tagus with the Belém Tower and Discoveries Monument as your backdrop
2. Exploring the monuments and museums (Jerónimos Monastery, riverfront area) as part of a slow walk along the waterfront
3. Tasting pastéis de nata in Belém and using Belém as a perfect spot to feel Lisbon’s light and riverside vibe

Are you more into food, history, or just strolling by the river?
