You can buy fresh fruit juice all over Thailand and it is delicious.
Vendors use freshly picked fruit and juice it themselves into the best tasting juices anywhere.
I like the fresh pomegranate juice. Pomegranate has many tiny pieces of fruit which is not easy to juice and very time consuming.
To be able to buy a whole bottle, already juiced, as well as other fruit juices, is one of the benefits to being in Thailand.
There is no excuse not to drink healthy juice which has a ton of health benefits.
