Sometimes it's hard to paraphrase an idiomatic expression without altering the meaning.

Let me use a different example.

If you said, for instance, "London is a great place to be on a sunny day", it would indicate that it's great to be in London on a sunny day. Perhaps it could be used as a slogan to attract tourists to the city. Or "London is the place to be on a sunny day" would

It is the infinitive use of one definition of "be". The American Heritage Dictionary has "2. a. To occupy a specified position: The food is on the table." You could rearrange that example as, "On the table is where the food is." This is like "London is a fun place [for one] to be."
