El Tacazo in Guadalajara is a no-frills taqueria where you go for quick, well-priced tacos like al pastor, carne asada and grilled chicken rather than a fancy sit-down meal. Expect counter service, limited seating and a mostly cash menu, so bring small bills and be ready to order when you arrive; the staff may have limited English so knowing a few Spanish phrases helps. Ask for salsa level and lime on the side, stick to cooked fillings if you are cautious about street food, and plan to go early or accept a short wait because it gets busy during evening hours.
