Well, if you're Stone Brewing Co. head brewer Mitch Steele, leading a beer dinner at Dallas' best bar and the restaurant with the best bar food is enticement enough. The Libertine Bar (2101 Greenville Ave.) will be the host of a five-course beer dinner starting at 7 p.m. Wednesday. Cumin grilled scallops, shrimp ceviche, beef osso buco and more will be paired with Stone's Ruination IPA, Arrogant Bastard, Imperial Russian
