As all Harkins theatergoers know, it's all about the Loyalty Cup! I do like the North Valley location, the only Harkins for which I have written a review. It seems just busy enough to stay open, but not so busy as to be hassle on a big opening weekend. It's not a brand new theatre, but it was built recently enough to have comfortable stadium seating.
Like all Harkins, the staff is young and inconsistent, but generally friendly. Concessions are expensive, but with good variety. A $5.25 investment in the Loyalty Cup will provide you with $1.50 drink refills for a full calendar year. A t-shirt deal, involving popcorn, is also available. Personally, however, I've never been willing to make that fashion statement.
Discounts are available at the ticket window for children, students and seniors. Discounted tickets are also sometimes available at Costco.
