Is it time to get off the peach at Mario's bandwagon? It sounds like it to me. I actually had pretty good peach at Mario's about a month ago, but I still had to work hard to convince myself that it was some great thing that I should get down on my knees for. Pretty good seemed to cover it fine. But more than that, if Mario's can't seem to know when it's making good peach and when it isn't, how can you really call it one of the great things to have in Chicago? Shouldn't you be making it that great on purpose, not just when your price-shopping happens to coincide with tasty peaches? This is a place that's picky about when conditions are right for making peach... but not because of flavor.
Lest you think that I'm being purely contrarian on Mario's, I think there is something that is world-class all through the summer, and that's Mario's watermelon. I think the canteloupe is pretty great too. And if it's easy to go have peach once a week and see how it is that week, go for it. But if you're devoting a lot of energy to catching the peach, I say, try the watermelon. I've had it three or four times this summer and it has never disappointed once.
