Have to agree, have just returned from Disneyland and as a family were really looking forward to eating at Inventions. We have been to cafe Mickey for breakfast and dinner in the past and on leaving Inventions both children asked why we didn't go there instead.
The restaurant itself is very nice and all staff we encountered were lovely, could not fault them at all, but for the price you pay here I would have expected a much better selection and quality of food, we also ate at Billy bobs, silver spur and plaza gardens and would say they were all better.
The biggest disappointment were the characters, they are very few and far between. We were in there for nearly 3 hours and as others have said we had finished eating and just sat there waiting. We even had to tell a member of staff we were missed by characters when they did come in.
To end on a positive, when the characters did get to us they were brilliant with the kids.
