As said by others, this is a small club but it still has all the usual amenities including free drinks, Milano cookies, wrapped cheese and crackers. And free wifi.
If you're spending time at the airport, it's well worth the cost of peace and quiet. A "day pass" also allows you access to any other United clubs on your travel that day.
Located between gates E6 and E8, which was conveniently next to my flight to Chicago O'Hare.
