I stumbled across this great website while looking for places to take my 26 students.
www.Menudeldia.com It has lots of info on restaurants and a section where you pick the area and it lists the Menu del dia in several restaurants and the price. It list the entire offering, 1st course 2nd course, bebida y postre.
It furnishes the name address and telephone of the restaurant.
I'm sure this will help people find places outside the typical museo del jamon and others listed on this site. I'm planning on trying out a few in March.
