I find that restaurants don't typically list their corkage fee policies on their site, so it is best to give them a call. I usually see it listed when they have some sort of weekday special, like $10 corkage on Wednesdays. There's an app that seems pretty updated with restaurant corkage fees (at least in my area) - CorkageFee. I check and just call to verify. I draw the line at over $40 to bring my own wine.
