Denver is lucky to have a lot of great French dip sandwiches available, but for a stellar classic version, head downtown to Frank Bonanno's French 75. First, there's the hoagie roll itself, which comes from the restaurateur's nearby bakery, LoDough. On top of that soft, chewy bread sits a heap of shaved, mid-rare rotisserie-roasted sirloin. The final kicker is the umami-rich jus to dip it in, not to mention the pile of crispy fries. Bonus: The $21 sandwich is huge, and it could, if you have the willpower, last for two meals.
