Cardinal Rule

You're walking down Tariff Street in the Northern Quarter and suddenly you're in properly executed American diner territory—all dark wood, good lighting, and zero pretension. Cardinal Rule takes the whole 'burgers and cocktails' thing seriously without the eye-roll factor. The menu reads like someone who actually knows their way around a kitchen decided to do straightforward American food, which means your burger arrives exactly how you wanted it, and the sides aren't an afterthought. It's busy enough to feel like somewhere people actually want to be, but not so rammed you can't have a conversation.
