Small plates dining and snacking is popular in many different cultures and countries, which each has the own name for it. In Spain they are called tapas; in Venice, Italy they are cicchetti. Typically enjoyed by local residents in the early evening after work, they are meant to be light dishes - sometimes just one or two bites - to be tasted along with wine or cocktails.
Some people will make an entire meal out of going from one bar serving small plates to the next, sampling a house specialty here and here for hours. Others will enjoy these light bites before then going for a full dinner later in the evening (in much of Europe, it is typical to eat dinner much later than in America, closer to 9pm - 11pm instead of 6pm - 8pm.) Sometimes these bars serving small plates will also have a dining room for full meals as well.

Restauranteurs in America generally take the small plates concept in a different direction, basing an entire, sit-down meal around small plates. Instead of ordering a standard 3-course meal (appetizer, entree, dessert), in a small plates restaurant you would order more like 4 - 7 courses in order to have a complete, filling meal. Chef Jose Garces popularized the concept in Philadelphia, Pennsylvania with his flagship Spanish tapas restaurant Amada. He then continued the concept with his other restaurants in the city, including Tinto, Chifa and Distrito, each focusing on a different regional cuisine yet always with a menu predominantly of small plates.
Other restauranteurs soon followed suit, and certainly in Philadelphia - as in other major cities - small plates restaurants are now everywhere. Gastropubs and bars are also often branching out from their typical nachos-and-burgers menus and offering more creative small plates options such as marinated vegetables, gourmet deviled eggs, house-made charcuterie and other "petite plates".

You make me want to travel to Italy again. I see so much good stuff on both travel and food channels, and then I read about it here and there, and it sounds amazing. So they too eat late, huh?
Yes, small portions at night would be great.
It's been my experience in Italy as well, that eating dinner late was more than norm. Many restaurants don't open in Italy until 7-7:30 for dinner, and don't get busy until after 9pm. (The one benefit of that, as an American used to eating earlier, is that I can usually show up at a restaurant right at opening time without a reservation and get a table!)
And yes, I think small portions do make sense late at night when you don't want to go to bed with an overly full stomach.
I think tiny portions make more sense in Spain where they have dinner at 10pm! You write that it's common in Europe to eat dinner that late. I was not aware of that. To me Spain stood out in that respect. What countries are you specifically referring to?
