As you continue to explore the Kanto region in Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee!, you will come across guards outside Saffron City that will want some tea.
The aromatic tea that they’re after has a slightly bitter taste but soothes a dry throat, and will, therefore, quench their thirst. In any case, it is needed in order to gain access to Saffron City.
Where To Get Tea In Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee!
Thankfully, the tea in Pokémon Let’s Go, Pikachu! and Pokémon Let’s Go, Eevee! is an unmissable item that you will be handed as part of your continued story progression.
You will firstly need to reach Celadon City where, having defeated him in Pewter City, you will bump into Brock. He should be left from the Pokémon Center, but you may need to beat Erika at the Celadon City Gym to be rewarded with the Rainbow Badge first.
In any case, once you have spoken with Brock he will give you a handful of items – one being the cup of tea that you will want to hand over to the guards (who will happily glug it down) and Pewter Crunchies.
