Named after William Drennan (1754-1820), doctor, political activist and poet (he coined the phrase 'Emerald Isle'), no doubt this visionary would approve of his namesake restaurant. The double-height interior gives this cosy spot a welcome feeling of space. Dark woods, greenery, curios and large artwork dominate; it's as though you are dining in a gracious townhouse (which, we suppose, you are). A pianist evokes a party atmosphere, particularly as the evening progresses and the wine takes hold. And the small, ever-changing menu delivers classy fare with a local touch. Definitely one of Belfast's best, yet little-known, eateries... hence the need to book ahead.
