Boardwalk

You're heading down to the Millennium Wheel area and stumbling into somewhere that gets the balance right—unpretentious enough that you don't feel awkward in your work clothes, but actually put-together. Boardwalk does the kind of food that works: think elevated comfort eating rather than anything trying too hard. The riverside location means you're getting decent views without the faffiness of somewhere trying to be fancy. It's the sort of place locals bring their mates to rather than dragging visitors to impress them, which says everything.
