At "Buns and Guns" you can order a "Kalashnikov" sandwich from a bullet-shaped menu, prepared by chefs in military fatigues with the roar of explosions as background music.

This new fast food restaurant in Beirut's southern suburbs was the brainchild of co-owner Ali Hammoud. He said the war theme was a novel concept that has nothing to do with Lebanon's recent history.

"It's just an idea I had, nothing more, nothing less. I could have put toys in place of the sandbags and teddy bears instead of guns. But it was just an idea," Hammoud said.

"You could say that the situation in the country made people pay attention," added Hammoud, sitting outside his restaurant, which has become popular with teenagers.

Guns, bullets and pictures of other weapons decorate the interior. The slogan "A sandwich can kill you", with a picture of a gun superimposed on a burger, is displayed outside.

Completing the war motif, sandbags surround the outdoor seating area. The menu features sandwiches and burgers with names such as "Terrorist meal" and "RPG", as well as "Kalashnikov".

"First time I came here, I thought it was a weapons shop. When I looked at the names of the dishes, I still thought so. I only realised it was a restaurant when I went inside," said 15-year-old Hussein al-Hajj Ali.
