Hello there ,
Depends on your budget of course . If you have a rent a car , we always visit Arizona Charlies Decatur for the Steak and Eggs Special in the coffehouse $3.99 24 hours . Nothing fancy , but a good meal everytime I've been there and a nice locals casino out of the way from the strip .
Hashhouse a go go , In and out burger are good also .
Do a search on here of Las vegas there are a few other threads that go into depth o some nice roadfood spots .
Also if you like Hot Dogs , the best I've had in Vegas is the cart dog in the Gold Coast sports book . If you are stating at Harrahs properties with no car , take the shuttle to Rio walk across street to Gold Coast for the dogs they are that good .
