The descriptions of characters’ eating habits recurring in Michel Houellebecq’s novels make a complex system of signs functioning at the textual and intertextual level as well as in reference to the extratextual reality, i.e., the situation of the Western society at the turn of the 21st century. The aim of this article is to identify the key points of this system and determine the possible directions of interpretation of these culinary motifs. For contemporary decadents from Houellebecq’s novels, lone feasts are a new kind of ritual, which – unlike the traditional “ceremonies of eating” – does not help maintain interpersonal relationships but only provides temporary relief and helps them forget about problems.
