Harakara's burgers are seasoned with only salt and pepper - no ketchup, mustard or sauces - so as not to mask the rich flavor of the aged beef. The Avocado Cheeseburger, the most popular choice here, is topped with soft, ripe avocados and tangy cheddar balancing the meaty flavors of the juicy patty.
Other, less traditional burger choices include onion-shiso and pineapple, and there are numerous toppings like onions and pickles, although they tend to add up - for example bacon is an extra Y450. Set menus are a good deal though - Y350-400 gets you a drink plus a side dish to go with your burger.
Burgers start at Y850 (for a plain burger), and everything on the menu is ready to take out. The shop is open all afternoon on weekends.
