Looking for a good but not too fancy place but not a hole in the wall either(we will be in jeans) near MCI center to have dinner. Husband and I are leaving the kids with grandma and escaping to the city to have dinner. We want to stay in the Penn quarter area. I know that there is a concert that night so we want to make sure either it's a place that takes reservations or its not likely to be too crowded. We want to eat on the early side. Any suggestions or which would you choose of the above?
