I’ve always thought Wendy’s was the best. They grind their beef on the premises.
Wendy’s does not grind their meat but buys it fresh never frozen.
Best of the chains. Expensive, 1st class local grille just 5 min. from us has $5 - 1/2 lb. burgers on Monday nights, and no one can beat them. Other local places too far exceed Wendy’s.
If I’m on the road, it’s Wendy’s for burgers. If I’m in town, it’s one of the local places......
