Mexican restaurant?

I am not much of an eat-outer and its always an embarrassment when a visitor questions me about good places to eat in town. But I was wondering if there is a good Mexican restaurant in town. Tomatoes, a Mexican restaurant in Ahmedabad is a wildly popular one and the cuisine is absolutely scrumptious. I still can't forget the nachos and tacos. Which also leads me to the following question. With the Indian palate clearly inclined towards spicy food and Mexican cuisine being a palatable example of one, whats keeping Yum! Restaurants from bringing Taco Bell to India? BTW, I must mention that the restaurant above serves only vegetarian mexican cuisine.
