It's a most undignified way to roll up to former California Governor Arnold Schwarzenegger's favourite restaurant. We arrive at Lucca, in Sacramento's leafy Midtown, hooting and hollering on one of those 15-person party bikes that resembles a bar on wheels.Usually, Sac Brew Bike's tours hit rambunctious pubs. But, our group has chartered the party bike to peddle the eight blocks from Sac Brew Bike's bar and headquarters to fine-dining Lucca.
