One of the best things to happen to Dublin in recent years was the influx of Chinese immigrants and the corresponding increase in Chinese restaurants. Many of these have clustered in Capel Street and, most of all, Parnell Street. (We don't quite have a proper Chinatown yet but with a bit of luck we'll get there.)
'Manna' is one of the Parnell Street restaurants, and I went there for the first time recently. It's very much in the style of the newer Chineses - compact floor area, very wide variety of main courses, and menus written in Chinese and English.
Price: Excellent - for example, I paid €9.99 for starter and main in the evening.
Service: Poor. Not warm, not attentive, missed some basics.
Decor: Simple but alright.
If you're in the area and want cheap Chinese food, Manna is fine - but if you're happy to spend a little more there's plenty of competition on the same street.
