For casual dining, the Hakone Open-Air Museum has a pleasant restaurant, Bella Foresta, overlooking the park's fantastic scenery and offering a buffet lunch daily from 11am to 3:30pm for ¥1,980. Also sporting a view is the even less formal restaurant Owakudani Sky, on the third floor of the Owakudani Ropeway Station, serving curry rice, noodles, and other fare for less than ¥1,200.
