I have eaten at quite a few different Sonics in Georgia and Florida, ALL of which were pretty good for fast food, never had any complaints, UNTIL I TRIED THE WALLINGFORD, CT LOCATION. I order a cheeseburger, fries and a bottled water. The wait was a little over 20 mins, the bun on the cheeseburger was cold and the meat was very hard. The french fries were cold and taste like they had been sitting under a heat lamp for a couple hours. I asked to speak to a manager and they gave me a complete new order, thankfully the second time around was better than the first.
