A former girlfriend used to live 2 blocks away from the SW Jefferson Ole Ole, and I had the pleasure of eating there fairly often. From quite early on the owner, who at the time seemed to work the Jefferson location fairly regularly, would recognize me, thank me for coming back, talk about whatever. The staff in general always seemed cheerful and close-knit.
I live much closer to the Burnside restaurant and eat there nowadays, and while the atmosphere on this side of the river isn't quite as familially chummy, the staff is still polite and friendly.
I can't say much about most of the food at Ol? Ol?. I've tried a couple different burritos which were very tasty, if not gustatorial revelations; my lack of a broad knowledge of the menu is due to my indefatigable love of the cheese enchiladas plate with red sauce.
The food always arrives about 2 minutes away from the enchiladas themselves cooling to a temperature at which they can be inhaled without fear of melted cheese burns. This is the perfect pause in which to mix, chop, and generally rearrange the plate's items into your favorite combinations (sorry, fussy ingredient separatists. You'll have to rea the Mercury or something. Although you're probably more the WW type). Once your plate is prepped, what you'll be eating is made with freshy-tasting ingredients--fluffy rice, crisp, unblemished lettuce, smooth and creamy refried beans--is generously portioned, and has a perfect ratio of side-items-to-enchilads-focus quantity.
I've enjoyed the plate with beef and pork enchiladas, but here as with enchiladas in general i feel cheese only is the true soul of the dish, which i've always seen as a combination of soft, easy to eat items that can be consumed quite rapidly owing to the fact that most of its elements are as soft and blended as though they had already been chewed. While this is not to recommend that you bolt the meal as fast as you can, or that I do with any regularity myself. It does, however make it an ideal candidate for hangover recuperation chow, and also works quite well when for whatever reason you've gone an unusually long time without eating, most of the things you consider eating seem unappealing or even a little nauseating. And at that point, who wants to add a lot of avoiadable chewing?
Pros: taste quality speed friendly staff affordable
Cons: cash only
