Something changed with the McNuggets (and perhaps some of their other menu items) over the last several years. I recently had them after not eating at McDonald's for a while and they were definitely less appetizing than I remember. The pancakes I had during another visit also tasted a bit off--kinda like the batter was oversweetened or something.
Oh and the prices went up significantly too. That 10 piece McNugget meal costed $8 something after tax. Not sure it's worthwhile to visit anymore considering all that.
