I love various kind of foreign foods, including Mexican food taco. I ate my lunch at Rubio's. We used to eat in this place quite a lot when we were in Pasadena. There is another Taco Del Mar restaurant nearby the hotel. So taco, taco, more taco. Wonderful. This device is new. After you order the food, take it with you. When your order is ready, it vibrates to remind you. I saw this in several restaurants now.
