We go to Oregano's for two things- Pizza and salads.  Tonight, we went for a giant salad and a piece or two of pizza.  When our waitress took our order, she said that they were low on romaine lettuce- (the main ingredient of  most of their salads) and asked if they could add some spinach. There were 5 of us, and most did not like spinach, so we were very disappointed, and wanted the manager to know.  He told us that he made 3 trips to the grocery store that day, and bought them out of romaine lettuce.  Then we found out they were not low on romaine, they were out.  I don't know how that happens, but it doesn't seem like that's a way to run a restaurant.  The manager knew that we were very disappointed guests, and did not offer anything to win us over or make us want to go back.
