This slightly random South Beach hotel bar is a reminder that martinis and cheeseburgers are one of life’s great pairings. Walk past the fancy restaurant in the lobby and up the stairs to grab a seat at Greystone Bar, which will most likely be populated by tourists and possibly a jazz pianist. The dark bar has a small “comfort food” menu, but you’re here for the smashburger (and waffle fries). The burger is straightforward but really well-executed—caramelized onions, pickles, american cheese, finely shredded lettuce, and two smashed patties. And the waffle fries are crispy, thick-cut, and evenly seasoned. Add a side of the house sauce. They don’t say what’s in it, but it’s spicier than most secret burger sauces, and goes so well with your fries, burger, and dirty martini.
