What is a Restaurant for Roast meat or BBQ?

There are many restaurants that specialize in meat roasting and barbecue. It may be helpful to ask your question again specifying a location. As no such region is specified, I'll answer with a couple chain restaurants that can be found in multiple locations across the country:

• Fogo de Chao - Churrascaria, or Brazilian Steakhouse
• Famous Dave's - Texas-style Barbecue
