Hello and welcome! We have done the Star Wars dessert party twice and love it. The first time, we were seated in front of Hollywood and Vine, but the most recent time, we were seated right in front of the Chinese theatre - best seats in the park. I believe that the seating area is permanently right in front since they now have the removable stage. If you know where that stage usually is, right in front of the theatre - that's where we were seated the most recent time we were there. Since the food and drink portion is in the Launch Bay building, it's nice to be inside. There is some savory food as well as desserts, so we tend to make it our dinner - yes, crackers/cheese/hummus/flatbread/fruit isn't the best dinner ever, but that combined with AYCE desserts certainly got us full and happy. Plus unlimited drinks? Yes $80 is a big steep, but if I have dinner with 3-4 drinks at a Disney restaurant, I'm going to be getting close to that cost anyway! Here's a picture from the current seating, this is not zoomed in or edited, it's just what it looked like from our seat.

We have also done the HEA one and the Illuminations one (about 2 incarnations ago). We felt like the Star Wars one with the new seating area was definitely the best 'deal' of the three - we are going to do the Frozen one again this year (current Illuminations incarnation) because I really want to get that center view of that show one more time before it might be going away...still hoping those rumors are untrue!
BTW....here's my post from the last summer's version of the show - yes the seating is more off to the side, but it wasn't all that bad.
