The Ipe Grill at the Hotel das Cataratas serves a buffet breakfast in the morning (included in every room rate), and a buffet dinner in the evening. The Ipe Grill also serves a la carte options for dinner in addition to the buffet, at least on Sunday and Monday nights when the Itaipu Restaurant is closed. Although we ate dinner at the Ipe Grill intending to order from the a la carte menu, the menu options were a smaller sampling of what was offered in the Itaipu Restaurant and at the same cost, yet in less formal surroundings. The dinner buffet was extensive and nicely presented, but the cost was a bit high at $65, not including drinks (the price did not even include a glass of water). The Ipe Grill has both indoor and outdoor seating, and reservations are essential if you want to dine outdoors by the pool, which is very lovely under the starry sky. (We made the mistake of not reserving a table for dinner in advance, thinking that because we were visiting in the height of the summer that it would be too hot and/or buggy to eat outside, which was not the case. We also had no idea what time we would be ready to eat dinner, and had we booked from home, we never would have expected to eat dinner as late as we did on this trip. We had no problem eating outdoors at breakfast-time, however.)
