I have a friend who lived in Bath for a summer. She loved this cafe. It's chic and casual. So after a visit to the nearby Jane Austen center, we walked up towards the Circus and found the side street that offered to lead to some of the same for lunch... but something different.
While the restaurant was full of people, we were able to find a table with a cushioned bench seat by the window. Though I liked the black tables and the paint splashed art on the bright red walls that made me think of Jackson Pollard, a family with children wouldn't be uncomfortable here. Spanish tapas are a specialty on the menu, but I opted for something vegetarian: a vegetables and feta sandwich full of avocado that was absolutely delicious. My husband was happy with a jacket potato and a pint to warm him up. (It was raining... of course.) I got tea for a quid fifty and lingered a while in the warm room.
Bottom line? This is an excellent choice for a quick, reasonable meal in a nice, relaxed atmosphere. The menu offers a bit more than your average pub, and the service is actually decent. I'd certainly eat here again when shopping or sight-seeing in Bath.
