One of Bath's most famous eating spots, housed in what may be the oldest building in the city. Sally Lunn's is known for its oversized buns — somewhere between a brioche and a bread roll — served with sweet or savoury toppings. The savoury versions with cheese, smoked salmon, or roasted vegetables make a decent light lunch, while the sweet versions with cinnamon butter or lemon curd work well with afternoon tea.
The building itself is worth seeing: a narrow medieval house on a quiet lane near the Abbey, with low ceilings and uneven floors. It gets busy, especially at weekends, and queues are common at lunchtime. You can visit the small kitchen museum in the basement for free. Prices are reasonable for what you get.
