The Library is a top quality steak house in a city packed with good places to eat. It is a little old fashioned but only in a good way. Given that if you're looking for inventive and imaginative food this is not the place. If however you want a good solid steak house with good service and a pleasant, relaxed environment then this is your place.
As for being "Expensive", well you have to pay more for top quality meat (and it is) and good staff who know how to cook it. In my view the prices are fair, good even, for what is on offer.
