Just went into the restaurant and there was a waiter showing the place to sit. The daily menu isn't big. The portions are big (200gr ~ 300gr) and delicious. If you want eat good and cheap I recommend to come to Pou Nou.

Parrilla del Pou Nou is a traditional restaurant located in the little town of Canyelles (at the road between Vilanova i la Geltrú and Vilafranca del Penedés), where you can eat typical food of Catalonia, for example you can eat "calçots" and do the "calçotada", a menu which include calçots (more or less large onions) with a romesco sauce, sausages with beans, some types of grill meat and catalan cream.
The menu is good, but you can not eat all calçots you want, I remember that you can only eat more or less 12 calçots. It is a good option to taste typical calçotadam but I think that there are some other restaurants in Catalonia (for example near Valls), where this typical menu is better.
