This tiny little restaurant off Oltorf is a wonderful, hidden gem. Although it's been getting more press lately, this family-owned restaurant has all you need for a non-stress breakfast or lunch.
Their breakfast menu has all your basics - bacon, chorizo, migas and breakfast tacos. But, if you're looking for a real treat (and are ready to throw out that diet), order their Chorimigas. They are a wonderful blend of migas scrambled with chorizo. The plate comes with papas (homemade fries) and refried beans. You'll fear a heart-attack as soon as you walk away, but will be in heaven while you're going at them.
Their lunch menu is also very good and cheap. You can get fajitas with all the trimmings for under $7. They also have really good and cheap daily specials.
