Times' food critic Frank Bruni hits both New York ballparks, rates the chow, and emerges pretty unsatisfied. Though it sounds like the eats are a mixed bag, Danny Meyer seems to at least prove that mass quantity food can be served with excellent attention to quality (Shake Shack, duh), though Bruni takes him to task for the predictable thirty minute wait. Frank should know that's only five minutes longer than we waited at Yankee Stadium on Day 2 for a bleepin' Nathan's hot dog, so this blogger isn't inclined to pin this only on this one proprietor.
It sounds like with a little focus, some re-jiggered recipes, and a little editing, the new parks can provide some quality niche products for those who want more than the traditional hot dog. Which, full disclosure, is our own preference.
