Hillstone's take on the French Dip is piled high with juicy prime rib. The meat is smoky, tender, and perfectly cooked, and its juice seeps into the soft roll. The dark, rich au ju, never too salty, is just a bonus. The accompanying shoestring fries are also pretty legit. For those of you who crave a kick, there is also a hint of horseradish in the mix, which can be applied judiciously if you so choose. This may be the priciest pick on the list, but it's well worth the investment.
