We stopped by the bar for cocktails & appetizers after hitting the mob museum. The bartender was friendly and made a great Aviator. We ordered crab cakes which were fabulous, the shrimp cocktail - huge and tasty, and the beef tartare - just OK as it was about underseasoned and dry. The ambience was fab, just I was expecting from Oscar. The piano player and guitarist topped off the old Vegas-style experience. Dining room seemed to be packed with tourists on a Saturday night, so I was glad we chilled at the bar.
