If you’re one of those Fish Taco fans who can’t wait for the gourmet Mexican restaurant to open at Wildwood Shopping Center, we’re sorry to tell you that the wait will be a couple of months longer than expected. “Nobody wants to open sooner than I do, but now I think we’re looking at the middle of January,” says owner Francis Namin, who opened the original Fish Taco on MacArthur Boulevard and also owns Food Wine & Co. in Bethesda. Namin signed the Wildwood lease this summer and had hoped to open by fall, but plumbing and electrical issues got in the way. Still, he promises the new restaurant will be worth the wait: modern decor, seating for up to 80 people, a streamlined takeout counter, and a “lighter, brighter and happier” look than the one on MacArthur Boulevard.
