Hilldale Pizza & Subs has been serving Haverhill from the same Hilldale Avenue address long enough that regulars measure their loyalty in decades. The menu centers on gourmet pizza—they describe themselves as constantly experimenting with new recipes—alongside chicken and steak subs made on buttered rolls, dinners with fries and salad, pastas, and jalapeno poppers. Repeat customers praise the freshness of the rolls and the consistency of execution, suggesting the kitchen takes its foundational recipes seriously.
