There's a viewing platform at the other end of the concourse.....when you leave Chef Mickeys, just keep walking straight towards the opposite end of the building, past the Concourse Steakhouse, the gift shops, etc. When you get all the way to the other end, you'll see a rather plain looking exit door. Go through that door and you'll be outside, under the monorail beam. This platform/balcony faces the MK and you'll have a nice view of Wishes. It's kind of a sideways view, but you'll see all of the fireworks very clearly.
