I have visited MacAlpine's a few times, and every time I have been very pleased with both the food and the service.  The wait staff and the owners are always very friendly and helpful and the food, although nothing fancy, is always good.  I love the atmosphere of this restaurant as well as the neighboring thrift shop that is fun to browse while the food cooks.  And the egg cream sodas are delicious!  Not to mention visiting a piece of Phoenix history at the same time - I love it!  The only downside to this place? I wish they were open later into the evening...
