For a chain Italian restaurant, the food at Louise's is really good. The lasagna couldn't be more perfect, and my husband thinks the spaghetti is great. The portions are huge, but try to save room, because their tiramisu is great. Surprisingly, the location on Melrose is pretty easy to get in, even on weekends. The Pasadena location tends to be more crowded, in our experience. If you're willing to sit outside, you're almost guaranteed no wait on Melrose at least.
