My husband and I were super excited to try this place. Great concept, but I hate to say, EXTREMELY (with more emphasis than my phone can type) poor execution. In their defense, it's a new spot and we were there Friday night at 730, but the less than mediocre tasting food couldn't even salvage the terrible service we received. We were told there was an hour and a half wait for a table for 2 so we gladly sat at the bar thinking we'd have an appetizer and a few drinks then move to a table later but we never got a call (not even after we left), which is inexcusable in my opinion. We ordered the "Fries, Fries, Fries" appetizer with extra sauces to try, and the super basic basket of fries came an hour later with no extra sauces. We could barely get someone's attention to order a drink despite being at the bar so requesting our forgotten sauces was a lost cause, obviously. After 2 hours and many desperate attempts to keep our glasses full we decided to order food to go, which was a joke. It took another 45 minutes to get our food and the food itself was abysmal. We ordered the bacon cheeseburger with the mac and cheese and an extra side of pasta salad and it was barely edible. I had high hopes but unfortunately Rosemont just didn't deliver.
