We went to the food court at 2450 Main in Irvine on Saturday intending to try the Italian Beef and / or the chili dog at Chicago's Best only to find out that they are only open five days a week (I'm going back tomorrow). Next to Chicago's best is a Greek establishment, and I apologize for not remembering the name. We decided to give them a try. I asked them if they made their own gyros or if purchased, from whom did they buy. I was gratified to find that they buy Athenian Gyros from Chicago. (My cousin's son used to work for Athenian, and I like it's flavor.) We opted for two gyros sandwichiches with a side and drinks. Came to about $20. Their tzatziki is served on the side (for better drip control) and could use a little more flavor, but all in all, a very good sandwich and worth a trip back to try the rest of the menu (they also serve felafel). Tomorrow I'm going back to Chicago's best. We'll see.
