Sonic is always a great stop! The service is quick, the carhops are friendly, and the food comes out hot and fresh every time. I love being able to grab a burger and tots or one of their slushes...

Order wasn't done right; food was sloppily prepared; lids on the drinks were barely on and milkshake spilled over the cup; server was such in a rush and practically threw the bag.
