Kathy's Waffle House is a long-standing Granada institution that serves exactly what the name suggests — American-style breakfasts — along with sandwiches, salads, and reliable coffee. It is where most travellers end up at least once, particularly for the morning meal before heading out to the lake or volcano.
The setting is a shaded terrace on a side street near the park. The menu is not going to surprise anyone who has spent time in Central American traveller hubs, but the consistency is genuinely appreciated when you've been eating rice and beans for a week. The owners are a good source of local information and the atmosphere is relaxed enough that a coffee and a waffle easily stretches to two hours.
