My wife & I dined at Le Caillou this evening, having previously booked online via Uniiti. We were made very welcome by both proprietors and dined outside in a family-friendly setting. The location (on the edge of the botanical gardens) and building (a modernist concrete pebble - hence the name?) are both slightly unusual. The food & drink was simple but excellent - high-quality locally-sourced ingredients presented in a tapas-style menu. Our only slight disappointment: the lack of live music - we had picked the wrong night!
