Since this is the original location, it is my favorite location, even if I don't live that close to it anymore. I don't know if Ralph's and Denino's planned being across the street from each other back in the day but it is a perfect strategy. Have the best pizza on SI and then go across the street for the best dessert on SI!
Since it is so popular, on a good night, expect to wait on lines. But if you never had Ralph's... just know there are lines for a reason. You won't be disappointed!
