Butcher Jr. by Lanpengyou Zhongshan is a shop in the alleys behind Zhongshan Station in Taipei that serves handmade burgers with aged beef patties and milkshakes. Its burgers include the sea salt milk candy burger and the garlic egg burger, served on house-baked brioche buns with garlic sauce. Customers order and pay at the counter first, then take a seat and pick up their food when a vibrating pager signals it is ready. The interior has weak ventilation, so a grease smell lingers after the meal.
