Where do you eat when you go to Paseo in Pasadena?
I've enjoyed the Mexican restaurant at the Paseo. They have good margaritas, the food isn't too heavy, and their house-made tortillas are excellent. Try a quesadilla. No, really. Trust me.
Roy's is certainly within walking distance, and may be the best bet for a good meal, though not inexpensive.
