Ordered delivery of a pizza and a salad last night. Pizza arrived without the correct toppings. Salad did not have the correct dressing.
Do they deserve a 1-star rating for a botched delivery order? Probably not. We've ordered from Potenza a few times in the past and have been pleased. However, I'm sure that establishments like this have a high turnover rate with employees, so the service and food quality may vary widely over a range of time. I guess best you can hope for from reviews like this one is to gain an accurate snapshot of the business at a particular point in time.
So, currently, it is a 1-star. There is nothing worse than waiting 30-45 minutes for delivery and then the order is wrong. Calling them back and yelling at them does nobody any good. Calling and asking them to fix their mistake doesnt work because you are starving and dont want to wait another 30-45 minutes for the corrected order to arrive. So the only thing to do is turn to Yelp and hope you can effect some change that way.
I'll probably give Potenza another shot some time in the distant future when I can be reasonably sure that the people who screwed up my order last night no longer work there.
