So back in the day, when Frontier was still active with RCT3 and we noted the problem of dining in that game, hoping that a future expansion would take care of it, there was a lot of discussion about Restaurants. Something we think Atari noticed and agreed with since last years announcements about their new effort has said there would be Restaurants.
There were numerous threads about how people would take several stalls, custom scenery around them to make it look like they were under one roof, in one open building with benches placed together, and then custom scenery of picnic tables, and then tables (some pieces not interactive with a peep because of the programming) to make a restaurant.
Thus this would be great to have in PC
Here however you should note that there are sit down restuarants, and fast food like restaurants where much as a stall, you get your food at the window, and then eat in the dining room. Extra staff, wait staff for full restaurants, busboys for both, and perhaps a chef to hire and effect the quality of the food and the type of food could be placed in the management system. (Chefs by skill, for there are now 5 star restaurants, 2 star michelin restaurants in theme parks) and of course some might know French cuisine, some might be sushi chefs, some good at TexMex...
If you dine at a stall with a dining area, your peep would spend a fraction more time than when just at a walk up stall. But in a sit down service, a lot more time, and white table service, with that top chef, a whole lot more time. As well as perhaps have access to the wine cellar with a selection of 2 buck chuck to a First Growth Bordeaux.
