There was a very good place around South William St? It was on a corner - can't remember the name but something typical like Taj Mahal - the whole place was quite open plan and airy, with steps leading up from the reception to the dining area.
Don't know if it still exists but had a few great meals there about 10 years ago.
Eastern Balti House (also known as Eastend Tandoori)? It was on the corner near Stephens Green Centre. It's now Maloti and not as good as it was but still tasty.
