How Robert’s Grill won everyone’s hearts
Robert’s Grill captured local affection through decades of consistency and community connection.
Opening in 1926, this family-friendly establishment survived the Depression, Dust Bowl, and countless changes in El Reno while maintaining its authentic charm.

The magic happens right before your eyes as skilled grill masters craft each burger on a well-seasoned griddle just three feet from customers seated at the 14-stool counter.
Locals praise the personal service and intimate atmosphere, with many customers becoming multi-generational regulars who bring their children and grandchildren for special occasions and celebrations.
What truly sealed their place in locals’ hearts was the accessible pricing and generous portions during tough economic times.
The original onion-fried technique – where thinly sliced onions are smashed directly into raw beef patties – created a signature flavor that competitors couldn’t replicate.
Customer reviews consistently mention the friendly staff, with some describing service from children who grew up in the business, creating a multi-generational family atmosphere that makes every visitor feel like part of the community. 👨👩👧👦
