I would definitely consider Dallas a fine dining town. As of a few years ago (and it still may be right) Dallas had more 5 star restaurants than New York per capita. As for support, if it is a truly good restaurant, Dallasites will pack it. There are restaurants of every type in Dallas, especially steakhouses. Some of the more famous and great places in Dallas are the Mansion on Turtle Creek (the gold standard in Dallas), the French Room, Riviera, Nana Grill, Old Warsaw. Check out www.guidelive.com to get a feel. Good wine lists are definitely appreciated. Age depends on the type of restaurant - the Mansion draws an older crowd (45+), while Steel (newer, trendy but very good) brings in a younger crowd (late 20's, early 30's). Any good restaurant would be a welcome addition, except a steakhouse. To say that market is saturated would be an understatement. WARNING: Restaurants may be the most competitive industry in Dallas. If you don't know what you're doing, you'll be gone in no time. It's not NYC or LA, but it's not far behind.
