I'm not sure ... there are so many.
Adjacent to 'The Forest', at the top of Harrah's, is 'Friday's Station Steak and Seafood Grill', which has an even better view of the lake. It, along with 'The Forest', are on the 16th floor.
Harvey's 'Llewellyn's' is another excellent place, with an even better view, because you can see Harvey's from 'Friday's Station' (blocking part of the view) ... here's a cut-n-paste:
High atop Harveys on the 19th floor, Llewellyn's offers a spectacular panoramic view and a beautiful presentation. The San Francisco Chronicle raved, "...one of the tops in dining on either side of the Lake." Open nightly for dinner, Llewellyn's offers an innovative continental menu. An exquisite Sunday Champagne Brunch is served year 'round. Llewellyn's -- Harveys culinary high point. Reservations are highly recommended.
