Its a sonic it can be hit or miss . But if you know sonic your getting your 1/2 price drink and getting on the road. Personally I would not hang out at this location. Do to the area but the staff is always friendly.

Love the huge variety of beverages. Would be great if there were always a discount/special on something- everything is So very expensive these days. I try to take advantage of the specials when I'm aware; my favorite is the $ 0.99 (milkshake or frozen drinks. I can't remember for sure- but I always get the milkshakes. Yum!)
