Would you go to a restaurant that only had one car in the parking lot?

Really! I want to know that answer. My son and I were on our way to Lum's, a restaurant that has been a South Florida icon for many years. There used to be several locations down here, but now there is only one. So anyway, we drove up to the restaurant and there was only one car in the lot. We decided to drive on by. Would you go in or would you have done what we did and go to another restaurant?
