Why did we dine here? – Montesacro is a hidden Italian gem, located in an alley right off a hardcore scary block of 6th Street in downtown San Francisco. The name comes from a neighborhood in Roma. We were tipped off about this place from a friend. Gianluca Legrottaglie, who runs nearby 54 Mint, opened this stylish restaurant, that transports you back to Rome, in 2015.
