About us

We started Senõr Onion in 2013 at the Blaauwklippen Family Market
where we sold hand made wraps made in our home in Somerset West. We soon realized that there was a market for TexMex food and so imported a tortilla making machine from El Paso, Texas. Our signature item has always been our tortilla basket, which is made from one of our wraps baked in a metal tin which we can then fill with a variety of food - from nachos to salads.

Before long our customers were asking for more and more variety, and today we have a menu comprising popular items from nachos baskets all the way to our wildly best selling chilli poppers. We make all our food in our shop in Somerset West so have total control as to what goes into our meals. Today, we boast a very loyal following of TexMex enthusiasts and are continually looking at ways to improve and add to our current menu, as evidenced by our recently introduced frozen food line.

And for those that prefer something a little less Mex and little more Tex? We've even started offering burgers with the option of fried chips! Just another reason to keep ridin' south of the border.
