Corkage in Scottsdale area???

Hailing from San Fran, corkage is an accepted, if sometimes expensive, option to a mediocre wine list. Having recently (last weekend) been in Scottsdale, was wondering how restaurants handle this as none of the restaurants we tried had a corkage fee printed on their menu (Mastro's and The Roaring Fork). Not bringing any with me (at least to the restaurants), I did not ask, but was wondering about the relative ease or general feelings that AZ restaurants have with this.
