Definitely check out the Saigon Deli at 1392 SR 7 (441) in Margate in the Dunkin' Donuts shopping center between Copans and Coconut Creek Blvd. on the east side of the road.
Great banh mi sandwiches and marinated grilled meats over rice. Don't skip the clear broth - great flavors. See more extensive comments in my posting in reply to Jennifer of Delray in early September '03.
They are closed Wednesdays, open until 10 pm the other days except for a Sunday 6 pm closing time.
The prices seem reasonable and the portions are satisfying.
Tel. number there is 954 975-2426
This restaurant compares favorably to the Vietnamese restaurants in Brooklyn where I live, where we have a big Chinatown with many people who identify themselves as "Vietnamese Chinese".
