Where can you get revive Pokemon Yellow?

In Pokémon Yellow, you can revive fainted Pokémon by visiting a Pokémon Center. Simply approach the Nurse at the counter, and she will heal your Pokémon, bringing them back to full health. Additionally, you can use items like Revives during battles or outside of them to restore fainted Pokémon to half health, though you can only use them outside of battle.
