Is Be Our Guest both Quick Service & TS?
If it is what is the difference between the experiences?
As the PP said, BoG is a quick service venue at lunch and a table service venue at dinner.
The West Wing and main Ballroom are used at lunch and dinner, whereas the Music Box room is only used at lunch (it was closed due to "enchantment issues" at the beginning of March).
At dinner, the Beast is available (usually) for a meet and greet in the Library (where the QS ordering kiosks are located). He's dressed in his ballroom finest. There is photopass photographer there as well.
The dining rooms look largely the same at either meal (same effects are on). The carts used to bring the food to the tables at lunch are used to display the desserts at dinner.
At either meal time, you'll wait on the drawbridge. At dinner, you wait until your pager goes off. At lunch, the lines usually forms on the drawbridge before going into the castle. Note that there isn't much shade on the drawbridge, so it can be pretty warm (or wet, depending on the weather).
I liked both meals at BoG. The food was good at both. In terms of atmosphere, it felt more casual at lunch. People are moving about because you have to get your own soda and cutlery from the stations. At dinner, the servers are moving about, but most guests are at their tables.
