I don't know why I keep going to this Sonic on North Harrison. The food is subpar in comparison to other local Sonics. The service is terribly slow. Several minutes go by after the service button is activated before anyone takes an order. I have driven away a few times because no one took my order. I have sent my food order back a few time because the order was wrong.
