We've eaten at Abuelo's in Amarillo on a few occasions and every time we've been there it's been a great experience! Great food, great drinks, great atmosphere! I highly recommend trying the green (tomatillo) salsa and chips - it's actually quite refreshing. For dinner, you cannot go wrong with enchiladas and their signature side, "Papas con Chile", which is essentially cheesy mashed potatoes. The restaurant is quite busy at dinner hour so make sure you're ready to wait for a seat.
