I've been a big champion of Ixcapuzalco but I must admit that I haven't been for a while, mainly because I went a bunch in a fairly short period last year/early this year. Since then a few people have complained that the quality has gone down and the cost has gone up.
I had lunch there today to see if the complaints are true. My thoughts:
1) I didn't have anything today that was best of, but it was all pretty good and showed the importance of fresh bright flavors (and the careful selection of items that produces them). The level of care put into the food still seems high to me.
2) Lunch was pretty reasonable for what I had, though considering that my lunch cost almost exactly what the whole family spent at Taqueria la Oaxaquena last night, reasonable is obviously relative. I'm sure it's the most expensive place along there, but I have no doubt you get what you pay for at lunch and that relative to dinner it remains a deal.
3) The dinner menu looked a lot more expensive, in fact climbing into the range of its River North sibling Chilpancingo. Still, this only seems like it's climbed to the level you would expect it to be at in other neighborhoods. In short, Logan Square is gentrifying...
Call me a booster but I say it remains a very impressive place and lunch, at least, is a pretty good deal.
