I have been to Regal Willoughby dozens of times. I love them even more after the remodel and assigned seating. I LOVE ASSIGNED SEATING!
Quick piece of advice. If you're going to see a popular movie on a Friday or Saturday night come early. Unless you're going straight to your seat. If you plan on getting popcorn or drink you have to plan ahead because the people behind the counters are slooooooooow! Generally the problem is they spend more time talking about nothing with each other rather than get the items. It's frustrating sometimes.
