Bakersfield is in the heart of California's conservative Bible Belt. There are more churches than hotels. Although there are plenty of motels because it is a pit stop between San Francisco, Los Angeles, and Las Vegas. Dining is largely limited to diners, fast food, and familiar chains. The area is generally regarded by folks in the big cities as "redneck."
Since Bakersfield is not a vacation hotspot by any stretch of the imagination, the range of accommodations is quite dismal. I would probably choose a Holiday Inn because they are fairly consistent in terms of cleanliness. If you can find a Courtyard by Marriott, then that would be fine as well.
Diner food isn't necessarily bad. But it can get old very fast. For fast food, definitely go to 'In N Out' Burger (a must for any visitor to California). And try to mix it up a little with hole-in-the-wall Mexican, Indian, Thai, or Vietnamese joints.
Just about the only attraction near Bakersfield is Red Rock Canyon State Park (Highway 58 East, then Highway 14 North). The scenery is right out of a cowboy movie. And the rock formations are impressive. If you have been to Nevada, Arizona, or New Mexico though, you have seen similar southwestern landscapes.
