Deep Dish Pizza near Vail
If its Zaccaza, most of us haven't been there recently, because in the past it had gotten so bad. I know they have been through many management changes lately, so maybe its improved (I doubt it). And I wouldn't accuse them of having a chef, everything use to seem like it came directly off the US Foodservice truck.
There is a new pizza place in Avon, Ticino in the Avon Center building (behind Avon Liquors). The pizza is thin crust, baked in a brick oven with high end toppings. The staff is very nice and the pizza is very good.
I suspect you're talking about Zacca Za!, in Avon.
If you search the boards, you'll find some discussion about it, although none it it particularly recent. I had lunch there a year or so ago and thought it was good -- not great -- but I'm more of a Neapolitan-style pizza fan that a deep-dish devotee.
