It's possible to make cafeteria/fast food restaurant with the university cafeteria station and community space lot. I have found that lot type as being the most versatile and it only needs the community board to function.
Would be nice if they added a new venue/lot type in each EP or at least enabled NPCs to the different food and drinks stations we have to appear on lots like the Museum or a Shop. I think giving the venues we do have more purpose would also help a lot. We don't really need a playground lot type for example, they could make the requirement very basic for park, like a bench, and then let the player decide whether it will be a playground, or community park, or national park, or whatever just by adding the different items and maybe adding lot traits. It would help if we had more playground equipment and more interesting things to do in a park. In TS1 we could have a cafe in the park and the jazz player, remote boat on the lake. In TS4, if want a working cafe in the park I need to create it as a community space and add a coffee stand. Sometimes there is a neighbourhood food stand nearby and I can use that but that's not always the case. Would be great if we could have NPCs for the bars, coffe bars, food stations, music instruments, spa equipment, even sales assistants, etc. appear automatically on any lot they are placed. Shops also need to be standalone, like restaurants, for easier stocking/updating, etc. After each pack I try and revisit my venues and update them with the new stuff if there's anything new that can be added. I don't mind the bars for example as long as I can make them a bit different from one another. One's a regular pub, one a bowling bar, one a karaoke bar, etc. Would have been nice to have a bowling table and a rocking bull attraction. Same with restaurants and even cafes, I like to give them a theme and make them different enough from one another, so to me at least, they don't feel like I visit the same place again and again.
