When eating a dish, I can usually identify the ingredients and spices by flavour, but different wines taste more or less the same to me. Some taste different, but I can't say that they taste significantly better than others. Spending $50 more on the food in a restaurant is going to make an enormously bigger difference than spending $50 more on wine. In fact, I find that not drinking wine at all usually makes for a better experience if the food is good, because the super strong flavour of wine destroys your ability to discern flavours on the next bite. Not all that different from putting hot sauce on all your food, in fact.
