Though Boston's Thai restaurants import a slew of flavors and recipes, Thai table manners don't always join the journey. Dating back to an era when every meal was shared, these customs mostly center on making communal dining an enjoyable event. The senior women in the group order for the entire table, picking dishes that fit each guest's flavor preferences. But you're not stuck with one selection. Instead, everyone shares everything and the dishes arrive at random, meaning diners each savor a few mouthfuls of one item and shortly move on to the next in an endless parade of flavorful fare. And unlike their Asian neighbors, Thai diners rarely use chopsticks—a fork and spoon, sans knife, is all they need. Above all, diners in Thailand should eat what they're served. Though deceptively innocent, food left on your plate indicates disappointment—an unlikely sentiment at these Thai favorites.
