Bonnie Ruth’s, a true gem of the Casa Linda shopping center which discreetly served up the most delicious seared tuna salad, oven baked pizzas and blueberry cake for years, has apparently closed. I dropped by Friday evening only to find the doors locked and a note from AmReit, owners of the Casa Linda shopping center, to the owners of Bonnie Ruth’s warning that (essentially) because they had not paid the rent, they were not to enter the property. Such a disappointment.
