Our order was wrong and the waitress did not make time to find out what was wrong. Issue: My wings did not have the sauce on them that was requested (instead were plain). When I asked to get a side of sauce, it took another 6 minutes to get it. This is the second time we have had issues with our order in as many visits. (First time, we asked for no cheese on spaghetti but it came out with cheese.) Overall, the food is ok but the service has not been impressive.
