At Block 7, dry-aged beef is topped with well-melted Gruyère and a bacon relish that adds a hint of smoke and edge to the already flavorful meat. The kitchen keeps additions to a minimum (arugula, Dijon aioli), and this restraint, plus an excellent bun from local Slow Dough bakers, keeps what could be an over-the-top burger from becoming pretentious. Block 7 also serves up toothsome sweet potato fries and one of the most reasonably priced wine lists in town, making the burger experience at the glass-lined Heights eatery an excellent one.
