As SDGourmand alluded to in another thread, this is José Andrés' "third" restaurant in the Cosmopolitan hotel. I thought I'd provide some info for interested parties:
It is an 8-seat table located within the Jaleo space. There are 2 seatings a night - 5.30pm and 8.30pm. The current price of the tasting menu is $150, "subject to change at any time". An email from their GM describes it thusly: "The menu and concept are unique to é by José Andrés. The menu will celebrate Spanish gastronomy in its most pristine forms. Chef Andrés crafts a culinary journey that unfolds through the evening using contemporary techniques applied to premium ingredients."
I'm fairly certain that é has instantly become the hardest reservation to secure on the Strip. 2 days after hearing about it, we tried and failed to get a seating for this week - reservations are accepted a month in advance, and I'm guessing that most spots are already booked. While we were eating dinner at China Poblano last night, their GM mentioned that Ferran Adria was visiting Vegas and would be cooking a few dinners at é this week - this undoubtedly contributed to the rush for reservations.
We look forward to trying é on another trip - it sounds like a different experience from Minibar and Saam. Until then, if you've been, I'm sure everyone else would be happy to see a report! :)
