Okay, I'm going to get slammed, but hey, if it's okay to ask where you can go that's child friendly, I'm going to risk it and ask the opposite. Here are my places to go eat with a nice patio where I'm in little or no danger of having my meal disrupted by the "little darlings" that haven't been tought how to behave in public...(I'm sticking to my neck of the woods, but would love to hear options anywhere, seeing as how the weather's getting to be patio time).
My favorite, before they renovated and blocked in the patio, was Eddie V's north. Even though they were in a parking lot, on a nice day it was a great place to enjoy a rasberry martini on the patio, have some outstanding appetizers and people watch. (still an okay place for happy hour)
Second place would have to be SXSW. Great patio, good music, decent food and drink.
Billy's on Burnett. Again, on a parking lot, but still an okay patio and I love the wings.
Cafe Bleu in Volente. Excellent patio, excellent food, perfectly calming in every way.
I think Chuy's North finally heard the outcry of its patrons and is trying to get obvlious parents to control their kids by putting up signs that say no free chips and sauce to kids that go free-range. They're also trying hard to seat the adults in back and let the families be up front, which is considerate. Yeah Chuy's for at least taking the first step! I wish more restaurants would be bold and make the dining experience pleasant and safe for everyone.
