LA GRANDE â A promising new chapter in the story of Raulâs Taqueria is about to begin in space that once housed a bookstore. The popular Mexican restaurant will soon double in size after the renovation of 1,000 square feet of space adjacent to it is complete. The restaurantâs new addition is set to open sometime next week. âWe are very, very excited,â said Arturo Escamilla, co-owner of Raulâs Taqueria with his father in-law, Raul Correa. The addition, which previously housed Looking Glass Books, will feature a bar with a porcelain tile surface and seating for 43 customers. Its features also include five televisions and ceramic tile floors.
