Vestigius has a great location facing the River Tagus. You can sit outside on the terrace downstairs or at the upper one where you will probably have a clearer view of the other shore. This place used to be a port warehouse and has been restored and decorated with vintage furniture and ropes.
This bar serves wine from several Portuguese and international regions, including fortified wines like Port and Moscatel. But they also serve gin and cocktails. To accompany your drinks, you have tapas.
Vestigius is more than a bar; you can attend a concert or an art exhibition and browse the antique books in the library.
