Having a house nearby, we have been to this Mastro's several times and have enjoyed the food every time. Being from Chicago, we know a good steak and they surpass any of the steakhouses in Chicago (Morton's, Gibson's, etc.). We had the prime rib at Mastro's for the first time last week and my husband and I both agree that it was the best prime rib we have ever had anywhere! We would give them 5 stars accept that the service can be inconsistent. On a couple of occasions the servers and hostesses came off as rather arrogant (like they were doing us a favor by serving us). This last trip we were given the option of being seated in the lounge right away or waiting 10 minutes for a table in the dining area. We elected to sit in the lounge, but it seemed that they only had one person servicing the entire area. It took a very long time for her to take our order. However, the food totally made up for this. Don't forget to have the butter cake!
