I don't go here often; once a month. But I really hate going.
One of the slowest service I've seen in any fast food chain. They have only 1 cashier in any given time and have 2 or 3 in the back just standing around while orders pile up.
It's not cooking staff; food come out, but servers are lethargic and uncaring.
I timed it once and it took 6 minutes for a big mac, 1:00 for burger to come out, 5:00 for them to bag it and hand it over. # of orders handed over during that time: 1. Msg to HQ, replace everyone, including the manager.
