The Sussex is a very nice restaurant with very good food. I've been there solo on business trips, and was last there with a group of 12 on a business dinner. Located right across from The Canal Bank Cafe, The Sussex is a different experience, where as Canal Bank is modern, The Sussex has an older, more pub like decor and atmosphere - and it sits atop a pub, so that makes sense. The food and service have always been excellent. The only complaint I can think of is that when I was there with the large group the restaurant became uncomfortably hot even though it was a very cold evening in Dublin - which the staff finally fixed by opening up some windows late into our meal.
