tml bring him to sentosa, botanical gardens.
His friend is flying off tonight.
TS, depending on your friend's interests, there are a lot of
places where you can bring him/her to.
Zoo and Sentosa are places which you bring him to only if you
have no idea what he/she is interested in.
For example, if he/she is interested in the arts, you can bring
him/her to the museum, though I will say that very few people will
even bother about that place.
