PARIS — A to-do list for a South Korean tourist visiting Paris:

Eiffel Tower? Check.

The Louvre? Check.

Pharmacie Monge? Check.

That’s right. Along with the city’s famous monuments and museums, an ordinary pharmacy in the Fifth Arrondissement, marked with the traditional green neon cross, has become a big attraction for travelers from South Korea.

They crowded the store’s aisles one recent morning as they often do, filling baskets with piles of face creams, skin lotions and lip balms, with smartphones at the ready to look up items online, and suitcases in tow to carry them all home.
