Visited here last Wednesday. It's quite small with not much seating downstairs. Seating for about 10 in front of the café, but there is a mezzanine level which seats quite a few more, by the looks of it. Good coffee, they have their own blend, and a decent selection of cakes and other snacks. They couldn't cope with a large group but OK for a group up to around 10. They are open every day.
Might be worth considering whilst Long Clawson and Hickling Cafes are shut. I’ve not been but the Vale of Belvoir Ladies have and recommend it. Prices look quite reasonable and it’s open everyday. https://www.naturescape.co.uk/wp-content/uploads/2019/09/A5-Menu110919.pdf it’s on Coach Gap Lane, which is on the left as you head out of Langar towards Harby.
