I've been coming here almost twice a week just to get their milkshakes. For only less than $3 you get this awesome milkshake that will have no problem in satisfying you. It's so creamy and thick (which is a plus in my book).
Service is also cute. Sonic is a drive in fast food place. You order on this machine by pressing a button and talking to an employee. Once you're done they bring out your order by skating over to you! Yes, the staff wears rollerblades. They give you the food and you pay.
Sonic is pretty cheap when it comes to food as well, but I'll update my review once I've tried a variety of items.
