Jack 37 Burger

Tucked along a side street in Nihonbashi-Kodenmacho, Jack37Burger builds its menu around the signature Balinese burger series, which pairs a fiery sambal sauce with sliced onions. Between nicely toasted buns rests a coarsely ground beef patty with a satisfying lean-meat chew that delivers the robust savory depth of a steak in every bite. The sweet, spicy, and tangy sambal cuts neatly through the richness of the beef, making the hefty burger effortless to enjoy down to the last bite.

The menu offers plenty of variety in its toppings. Among the crowd favorites, the Balinese Avocado Cheese Burger tempers the heat of the sambal with buttery avocado and rich melted cheese, creating a well-rounded harmony of flavors. The namesake Jack Burger takes a direct approach, layering the patty with a fried egg, cheddar, and sambal sauce. Variations include combinations with fresh coriander or sautéed mushrooms, while mild choices such as standard burgers and a housemade teriyaki burger cater to those who prefer to skip the spice.

Paired with a side of French fries, a draft beer, or a distinctive root beer, the meal takes on a classic diner feel. Inside, a compact dining room fitted with counter and table seating offers a relaxed setting well suited to solo lunches or casual dinners. Takeout and pickup options are also available, making it convenient when you want to enjoy a substantial gourmet burger at home or the office.
