The Oakcrest has been around for a long time and I know a lot of people like it, but it just doesn't do it for me. I work right down the street, so I met up with some people for lunch recently and boy did I regret it. I should note that this was not my choice to begin with, but I was willing to give it a try.
It is true that there isn't a lot of seating, but it wasn't extremely busy when we got there and our service was fast. We were in and out in a little over a half-hour. I agree that the staff didn't seem particularly friendly or happy, but they weren't rude either. I had a chicken sandwich with bacon and no side, while my four companions had burgers with fries or cheese curds. Everything was typical greasy bar-fare. I tried the curds but not the fries. The flavor was good, but it was so greasy and salty that my mouth was burning by the time I was done and my gut was already churning as we walked out to our cars. I was miserable for the rest of the afternoon. One member of our party felt the same, but I believe everyone else enjoyed what they had.
In all fairness, I know my experience is a fairly individual one. I eat very healthy food and I hardly use salt when I cook or add it when I'm out. If you typically eat like this, you'll probably love it. I probably would have loved it before I shifted my diet away from this kind of food. However, I do enjoy burgers and fries at places like the Great Dane and the Grumpy Troll, where they aren't grease-laden and loaded with salt. If you have a diet more like mine I wouldn't suggest eating here. I don't plan on going back, but I still give two stars because my experience my not reflect yours.
