|Now this is what a classic, old school cocktail bar is all about in San Francisco - though The Big 4 is also a restaurant, attached to the Huntington Hotel. The Huntington was originally set up in the 1920s for apartments, and some still function as such. The Big 4 is named after the four major railroad barons of Nob Hill/the Central Pacific Railroad, and the theme inside the place is old SF money elegance. The bar is decorated with old framed posters, dark wood, interesting sculptures, low lights, and a large piano bar area in front. Further back in the bar they use a two-group Rancilio to pull shots with a barebones thin, light brown crema (no surprise for the cheap choice of Peerless beans). It has a flavor weighted heavily in ashiness with some tobacco notes. Served in delicate Dudson fine china. Why a place like this charges $4.50 for an espresso and serves rot-got Peerless Coffee beans is beyond us.
