My information might be out of date, but it might be a starting point. There are three hotels in Thurles- the Munster, the Anner and ?? ( cant think of the name of the third- its in the square). These all used to do the usual meat, veg and spuds type meals. There is a big chinese restaurant called Jumbos which was good ( I'm not a fan of Chinese food, but this was very good). The Brewery, a relatively new gastro pub type place, used to have an evening menu which was nice. For a very good restaurant you could book Inch house which is a few miles outside Thurles- this has won awards and has a lovely country house atmosphere. I know there was a restaurant in Thurles which did unusual meats like Ostrich meat, wild boar etc but can't think of the name of it. I never ate there so can't comment.
