The prototype plastic shields are known as the "Plex'eat," and they resemble big clear lampshades suspended from the ceiling. They are being showcased temporarily at H.A.N.D., a Parisian restaurant seeking a way to reopen its dining room as coronavirus restrictions are relaxed.

As restaurateurs around the world seek to resume in-person dining amid the pandemic, they want to adhere to social distancing rules while also trying to serve as many customers as health and safety measures will allow.

Some are putting mannequins at every other table to put some space between the actual customers, like at Augustas and Barbora, a restaurant in the Lithuanian capital of Vilnius. Some of its faux diners are dressed casually, while others look as though they are at a ball. The clothes showcase the work of local fashion designers.

"We want to fill the space with fun things," said owner Patrikas Ribas.

Vilnius Mayor Remigijus Simasius called the initiative a "perfect match of communal spirit and creativity working side by side."

In Hofheim, Germany, the Beef'n Beer is using large teddy bears seated at some tables to keep diners properly spaced apart. They also ensure a cozy, less-sterile atmosphere.

At Amsterdam's Mediamatic restaurant, the owners have erected small glass houses that surround each table, served by waiters in protective shields.

While many restaurants offered take-out and delivery during the health crisis to keep generating at least some income, such practices are less common in France, although Michelin starred chefs such as Alain Ducasse have started doing take-out service.

Owners are seeking solutions that will coax back customers while also easing their anxiety about catching the virus.

Other creative solutions by restaurants across Europe:

At El Salamanca, a Barcelona beachfront restaurant known for paella, menus are gone and customers use their smart phones to scan a QR code to consult what is on offer.

Greek restaurants are using salt and pepper sachets inside of shakers, and menus are either thrown away after each meal or are laminated and wiped down regularly. Many waiters have face shields. Some tavernas have staff in matching face masks.

In the Russian city of Nizhny Novgorod, a restaurant on the banks of the Volga and Oka rivers has set up 20 plastic huts for couples. It is awaiting approval from authorities to open if it meets safety standards.

Italian restaurants are using contact tracing. Diners are supposed to reserve tables ahead of time and owners are keeping their contact information: If someone subsequently reports testing positive, the restaurant can quickly identify and contact those who ate there at the same time.

Some coffee bars in central Rome also are attaching stylish arched glass partitions to divide tabletops down the middle.
