The "M" in MShack is for Medure — the last name of brothers Matthew and David, who own high-end restaurants Matthews in San Marco and Medure in Ponte Vedra. In 2011, the siblings opened the fast-casual boutique burger spot in Atlantic Beach; a second MShack will open in St. Johns Town Center by the end of the year.
For minimalists there's the simple but tasty M Burger topped with melted American cheese, crisp lettuce, tomato, pickles and Shack Sauce. At $5.50, it is small but fresh — the Black Angus beef is 100 percent all-natural and ground in-house. For the uber-fancy, the specialty Medurable burger boasts savory foie gras and caramelized onions, carrying a hefty $18.95 price tag.
Even if you're not a burger lover, MShack's menu has an assortment of topped hot dogs, a grilled cheese sandwich (add applewood smoked bacon for an extra dollar), a fish sandwich, a marinated chicken breast sandwich and homemade Italian sausage topped with sautéed onions, peppers, mushrooms and melted provolone cheese.
Craving something healthy and pleasantly filling? Try the ginger-sesame dressed Super Kale Salad chock full of crisp diced apples, creamy cubes of avocado, shreds of carrots, onion, pecans and raisins. A fresh roasted beet salad comes with creamy goat cheese and raisins atop peppery arugula.
From the carb column, the house fries, queso-topped fries, sweet potato tots, truffle parmesean fries and even onion rings beg to be paired with your meaty burger or hot dog.
To complete the experience, a thick hand-spun milkshake is an absolute must. Available in small and large sizes, the pecan pie shake with chopped pecans reminded me of fall in a cup. Go simple — strawberry, vanilla or chocolate — or step it up with funky flavors like bananas foster, marshmallow brulee or peanut butter.
The separate relaxed bar area hosts happy hour 3:30-5:30 p.m. weekdays with $1 Pabst Blue Ribbon beers, $2 drafts or $3 glasses of house wine. Several craft beer are also on
MShack's beach proximity makes it perfect for pairing lunch or dinner with a stroll along the Atlantic Ocean.
