Guillermo's Double L Restaurant was founded in 1948 as a small drive-in with curb service, across the street from the current location. In 1970 drive-in service was ended, re-modeling was done and the business became a full service, sit-down restaurant.

During the subsequent years the restaurant was enlarged and re-modeled several times to become the large, modern facility it is today, seating two hundred guests.

Today, under the leadership of Cynthia Genematas, who is third generation of the founding family, the restaurant is proud to serve Authentic Sonoran Style Mexican Food prepared with only the finest ingredients. Also available is a full service bar, including award-winning margaritas.

Guillermo's is presently in it's 56th year of operation. The business, management and staff look forward to serving you and your friends.
