A recent trend(趋势) in Californian restaurants shows new eating habits among those people out to have an interesting dining experience. Appetizers(开胃品)seem to be the name of the games as diners turn away from the more traditional three-course meal in favor of smaller snacks served in various types of restaurants, bars and cafes. In this way, in the course of an evening out, you might go to a restaurant for a tasty dish to eat at one end of town, to a bar with some live music at the other end, then for a coffee, and finally back to the restaurant for a further appetizer.
Reasons for this trend are the fact that so many different types of restaurants have been set up recently, each with their own particular type of food and special atmosphere, together with the increased specialty in the type of snacks being offered. Gone are the cheese sticks of the old days, when appetizers were not really taken seriously. Some favorite snacks of the moment are slices of hot pizza, creamy fish-based dishes and crispy cakes and so on.
Prices for appetizers are not equal to a full meal; however, their new popularity has meant that they are by no means as cheap as they used to be. Certainly, for that special occasion, a meal in a nice restaurant, complete with the piano performance, is hard to beat. However, if we see this trend for “butterfly eating”---moving around several different places in one evening continues, then all the traditional style restaurants may well have to provide their own appetizer bars as well!
