We visited at 2:30pm on Saturday (New Years Eve). There are a few floors of seating so we were seated straight away on the top floor. The building is very quirky in its wonky small way. The staff were exceedingly polite and friendly :) Time wise we were there for a total of 50 minutes, and this was relaxed, just excellent service.
We both ordered the Quick Lunch of soup & a savoury Bath Bun. Our drinks were with us quickly and the food just as quick after. The smooth vegetable soup was delicious - and just the right amount as we also had the bottom half of a large bun to eat! I had the Welsh Rarebit Special - a toasted bun with gorgeous melted cheese on top as well as mushrooms and bacon. My other half had one with cream cheese and salmon - also nice.
You can even visit the museum & shop and take a Bath Bun home with you! I wish I had done this. I highly recommend eating here. Thank you.
