I’m here 5/4/26 around 2:30 with my best friend in between finals. We always come to Sonic- it’s multiple times a week. We always like it but I’m not sure who’s cooking today but please have them cook forever and give them a million dollars or something. The ice cream tastes like I should pay $20 at least. Extra vanilla, thick and creamy, cookie dough tastes like hand rolled. I’m not even trying to be dramatic but my mozzarella stick pull rivals that of those viral TikTok videos. I’ve eaten mozzerella sticks at Sonic for like 20 years. This is the best one of my life. #effatripledipper I’m not even trying to glaze I’m just kind of shocked by how good it was- my friend said the cook has a love for the craft comparable to Jesus’ love. Just like wow guys this was awesome. You have illicited quite a response from me I’m not even high or drunk I’m just high on Sonic.

Food was fine, the chicken burger didn’t taste so good. It was on the burned side, also they didn’t put on pickles. The bacon burger was very good! Fries were fine as well.

We went around 1:45 in the afternoon on 4-20-26 and ordered 2 Jr hamburgers , one patty was slightly overcooked and the other was so overcooked that the patty was charred (burned) and actually had shrunken . As to not embarrass the cook we decided to not send burger back , will not recommend this Sonic .
