A relaxed, dog-friendly marina restaurant with excellent views, generally warm service and appealing British comfort food, though a few dishes and occasional operational decisions have disappointed diners.
No. 1 Harbour Square delivers solid food quality anchored by seafood, pies and roasts that earn consistent praise, paired with attentive, professional service that keeps diners satisfied. The waterside setting with harbour views provides genuine appeal and comfort.
No 1 Harbour Square is a relaxed, independent waterside restaurant where the marina does much of the scene-setting: diners repeatedly describe sunshine, boats and harbour views that make lunch feel like a small holiday. The room is comfortable, the outdoor seating is a major draw, and service is usually warm and attentive; one diner even highlighted the pleasant surprise of full table service for drinks outside. The cooking leans toward accessible British comfort food and casual seafood rather than formal or experimental dining. Fish tacos, fish and chips, pies, squid, roasts, sandwiches and desserts dominate the praise, with several diners calling out fresh ingredients, generous presentation and good value. The record is not flawless: a few guests found particular light bites, accompaniments or a roast underwhelming, so dish selection matters more than the setting alone might suggest. Families should find the venue welcoming. Reviews describe enjoyable meals with children, successful adjustments for picky eaters, gluten-free choices and a vegan burger, while familiar dishes such as fish and chips, pies, burgers, wraps and desserts offer plenty of approachable options. Outdoor seating is also dog-friendly, making this a practical choice for a relaxed family or dog-walking stop by the marina.
