Angers eats well without making a fuss about it. The city has a solid restaurant scene rooted in Loire Valley produce — pike and sandre from the river, Anjou pork and duck, local cheeses, and the wines of Savennières and Anjou-Villages at prices that undercut anything in Tours or Saumur. The streets around Place du Ralliement and the old quarter near La Maison d'Adam have the densest cluster of restaurants; Rue Saint-Laud is a reliable stretch for lunch.
Markets are the best starting point for understanding what is in season. The Saturday market at Place Louis Imbach is large and genuinely good, with producers from the Maine-et-Loire valley selling directly. There is also a covered market near the train station open most mornings. Book ahead for dinner at the better restaurants on Friday and Saturday evenings, when demand outstrips capacity.
