The lemon cream color tastes like lemon cream pie! Delicious. I like the fact they offer several sugar free flavored syrup for those with sugar sensitivity.

I'm a big fan of the route 44 size. They are so large you can pour out half the slush and put it in the freezer for another time. One of the big draws here, for me, is their happy hour from 2-4pm. All the drinks are 1\2 price. So for that and the drink menu, I give it 5 stars. I enjoy all the different options and flavors of drinks. I always order extra fresh fruit to enhance the fruit flavor. You can request less of the sugary syrup that way. Some of our favorite food choices are the hot dogs. I love the footlong Chili cheese dog. I'm not sure why they call it a coney, as I have been to Coney island and they have 2 different tastes. Nonetheless, all the hot dogs are delicious. Their burgers and burritos were pretty good too. Not a fan of the chicken chunks. They always seem to be dry and overcooked. I occasionally I find the oil used for frying the tater tots and mozzarella sticks to be not fresh. When the oil isn't fresh it leaves a funky after taste in your mouth.

Drinks were great. Hot dog tasted old and the texture was weird. Tots were good, but not enough of them. Hardly any Fritos in the Fritos wrap. I'm used to Sonic being much better than this.

Typical fast food. The hot dogs are much smaller now and extremely salty. Drinks are always delicious.

First time trying sonic and saying the food was atrocious is being generous. Everything was cold from the SONIC® Cheeseburger Combo, the Tots and fries. The limeade was near undrinkable and the fries were very cold and over salted.
