31．B 细节理解题。根据第一段“When first entered, Vanak Restaurant does not look like much of a restaurant, but once the pleasant smells of kabob(烤肉串)hit the senses, you are incapable of calling it anything less.”可知一走进饭店，就可以闻到烤肉串的香味，故选B项。
32．A 细节理解题。根据第五段“A common sight is that of old Persian men sitting in the corner talking loudly about world topics, watching news events on TV, drinking a black tea”可知在饭店除了吃饭外还可以看新闻，故A项正确。B项与“drinking a black tea”不符；C项与“reading local Persian newspapers”不符；D项与“talking loudly about world topics”不符。
