If Disney really wants to go ALL IN on the Star Wars theming here are a few suggestions:
1) Get rid of the entire streets of America area. Nothing goes on there ever and I find people sitting on the stoops of the home facades to relax or eat. That does not inspire you to see more or spend money.
1a) In place of the streets of America they can use that entire area and turn it into a Star Wars themed area. Since you have the Tatooine traders right next to Star Tours then that would be an easy transition into making that into a Tatooine themed area. But what does Tatooine have to offer? Easy...
1b) Mos Eisley Cantina. We know this has already been discussed. It would be a great counter service restaurant and a great place to buy adult beverages. It has to match almost exactly except for maybe another bar that would be a counter service ordering place.
The main bar would serve the adult beverages and of course non-alcholic ones. There are so many great names to play off of with those adult and virgin drinks (Jawa Juice...which is mentioned in Star Wars E1, etc.).
They could also make their own version of Blue Milk which would need to be a great tasting drink that you would just HAVE to try.
I even think Disney may want to get into the Micro Brewery business and make a line of beers call Empire's Finest, or Emperor's Finest, etc. Imagine a beer that you can ONLY get in DHS made by Disney or just FOR Disney with a keepsake glass. It would be one hell of a draw and would keep the adults interested longer.
1c) You can have cast members wander in and out like clients in their Star Wars character costumes. Have a corner booth reserved for Han Solo and Chewbacca. The two may never show up....but Chewie might. You see Han is otherwise "predisposed"....see Jabba's Palace below.
1d) The Cast Member characters could get into a bit of a bar scuffle every so often. Nothing too crazy, but enough to have StormTroopers show up and escort them out. And every once in a while a few droids come in and the bartender could tell them "we don't serve your kind here". That could basically be your floor show. There is so much that could be done.
1e) The Cantina band is a given. Either animatronic or actual cast members playing to a recording. Imagine walking into the bar and hearing the famous Cantina Theme. It would teleport you immediately into the world of Star Wars.
2) While you are re-theming Streets of America...you could set up traders and vendors like on Tatooine selling different foods, very unique looking and themed foods for this otherworldly place. Souvenirs could be sold at these stands, stray robots putting on shows. A build your droid area, etc.
3) Down the road.....off in the distance...some great force perspective....Jabba's Palace. That is your new restaurant. Table Dining and an excellent experience. Similar to Mos Eisley Cantina, but very different.
3a) First you can have a huge animatronic Jabba and Salacious Crumb on his throne. Every once in a while Jabba can laugh. He can interact with the cast members and suddenly Jabba will bellow something and ALL of the staff will stop and listen to him. Just a great way for the figure to interact with the environment. Of course he has to speak in Huttese. No English.
3b) On the far wall, eerily lit.....Han Solo in carbonite. That is why he never arrives at his booth at the Cantina. One bounty hunter on guard at all times. Boba Fett would be a GREAT draw here for a photo spot. The CM photographer would also be in character as one of Jabba's minions.
3c) The Max Rebo band playing great music with Sy Snoodles as animatronics throughout the meal.
3d) Dancers in the middle of the floor...not as scantily clad as the movies of course, but that is your floor show...until....
3e) Different bounty hunters show up with characters they caught to present to Jabba. It would be really fun if they would grab a person from their table and take them to Jabba to present them as tribute. That person would be lead off and be missing for a bit....then taken in back and given something special including pictures of themselves being presented to Jabba. Personally.....I LOVE the idea of a picture of them in front of a giantRancor and put in the Rancor's hand. That picture would be priceless. You could even escort out the entire family or couple or whoever was at the table. This should be totally random and for adult couples as well as couples with kids. Kids always get picked for this stuff and the adults would love it just as much, if not more.
3f) It would be great if, every so often, Jabba would bark something and then hit a button and one of the dancers would fall through the floor and you would hear the Rancor roar from below.
Consider something like this similar to the meteor shower in T-Rex. Every so often this will happen so you will always get to see it during your meal.
Jabba's Palace would be SPECTACULAR.
more to come......
