When Miss Saigon opened in Coral Gables in 1997, most South Floridians were more familiar with the Broadway musical of the same name than Southeast Asian cuisine. In the past two decades, though, Miss Saigon has helped familiarize Coral Gables. Pho might not yet be as ubiquitous as foreign foods such as hummus or sushi, but Miss Saigon's six varieties of the northern Vietnamese beef soup have helped right that wrong one order at a time. The dinner menu lists a wide range of dishes, including an inspired vegetarian section with a $21.95 seitan watercress that's worth a drive. The weekday lunch special from 11:30 a.m. to 3 p.m. is more economical, offering 23 items — from bun (rice noodle bowls) to pad thai — for $9.95 to $12.95.
