Went to the new Sonic in Parma on opening night. The staff was fast and friendly. They performed very well considering it was their opening night and the place was slammed with people. We had to wait in a line of cars for about 20 minutes before we even got a stall. As expected on an opening night though.
We got the biggest and best cheesburgers and sides money could buy there being Sonic virgins. All in all I'd say they came in a very strong second place in that area along Snow Rd. which offers 5 different cheesburger options. First = Burger King "Triple Whopper", Second = Sonic "Super SonicBurger", Third = Wendy's "Triple Cheeseburger", Fourth = Eatin Park "Double Cheeseburger", Fifth = McDonalds "Big Mac".
Not the best value for the money in the end and not the worst like Eatin Park or Mcdonalds though. The burgers were satisfying and the meat taste like a hamburger should. Sides were pretty average... tater tots with cheese and onion rings with ketchup. The drinks were tasty they have HUGE variety of slushies which we loved. Certain that above all else is Sonic's claim to fame.
Ultimately you just end up paying a few dollars more than usual for the insurance required to cover the "car hops" (waiters/waitresses on skates) should they take a spill and go on workers comp for a few weeks. You get an experience that is perhaps a little more interesting than the Burger King drive thru window but a burger that's not quite as good. So if that's your thing then Sonic is a good bet on Snow Rd. Sure wish we had a 5 Guys a little closer to my house! =P
