Personally, I adore Cook, Serve, Delicious. Bought it on release on Steam and have not been disappointed. It's pretty much done and complete, with the dev working on his next game but coming back to do occasional bugfixes that pop up.
If you want to do well, you need a reasonable memory (or very quick reading skills) and semi-quick typing skills. The difficulty changes based on how well you cooked the previous day -- each successful dish put out increases the buzz by 0.5%, each bad dish decreases it by the same amount. Exceptions are rush hours (12-1PM and 5-6PM) which increase customer amounts and can be fast and frantic, and the Platinum star which gives a permanent +40% to buzz (but by the time you get there, you've pretty much beaten the game).
Minimal planning and no options to decorate the restaurant as you want. Buy new foods, upgrade them to get better and/or more ingredients, keep an eye on menu rot (decreased attraction with the majority of foods if they're on the menu more than two days in a row). The keys for varying items are rebindable so you can change up what items are linked to what keys -- if you're trying to change the keybinding on a level 1 food and can't, it's probably because a higher level ingredient is using that key.
Linear progression -- if you buy and upgrade enough foods, get enough combos, pass the safety/health inspections, complete challenges, you'll end up as Platinum Star pretty quickly. I'd say you're looking at 15-20 hours to max out the game fully. Money becomes a bit of an issue later in the game, but there are in-game bets to buoy that up, as well as rewards for perfect days.
But realistically, for $1? Unless you absolutely hate the idea of pseudo quick time events and being pushed to do things better and faster, it should be worth a look-in.
