Welcome to planDisney, James!
I am literally SO excited to hear that you have a reservation for
Steakhouse 71 in September! AHH! This is one of my all-time favorite restaurants at Walt Disney World. I am always so satisfied with my meals, and I love that it's not a huge restaurant. It's nice to escape the crowds for a little bit... it also helps that the food here is *chef's kiss* for sure.
Another thing I adore about Steakhouse 71 is that the wait staff is SO friendly and extremely accommodating! Whenever I have had a special request, they are always eager to make things work -- I have even ordered something from the bar menu before with success while in the main dining area. James, I would say that you have a very good chance at getting your Stack Burger from the bar menu while at dinner. I cannot guarantee anything as it will be up to the discretion of your waiter, but if you ask kindly (and it falls under what your waiter and the management system can allow), you should be sinking your teeth into that delicious Stack Burger without a hitch!
If you decide that you want to try something from the dinner menu I (as a red meat loving lady) cannot recommend the
Vegetable "Wellington" enough. Yes, it is a plant-based menu item. Yes, you will probably think I am silly for recommending a plant-based item from a steakhouse. BUT if you (or anyone else in your party) try it, you will not be disappointed. Both my husband and I only order this from the menu when we visit. I'm getting hungry just thinking about it!
I hope you have a lovely trip, James! If you have additional questions, feel free to visit us again at planDisney!
See ya real soon,
Allyn
