I agree with the last reviewer. I have been coming here for decades and always felt that their gyros were the gold standard. I went there last night with my kids and something was not the same. The pita was perfect, the sauce was the same, but the onions and the meat seemed different. The onions were cut very thin, paper thin--they used to be thicker. They also had a slightly bitter taste, which I don't previously recall. The tomatoes were mealy--so much so that I had to take them off. The meat also seemed different as well. It's hard to put my finger on it, but as I was eating it, I thought to myself "this is what baloney would taste like if it was made with lamb..."
Not the Parthenon I remember.
