It's good...
...but it has some major flaws:
1) Lack of meat storage. Normally at a fast food taco shop you just cook tons of meat and keep it warm. This is not possible here. Instead i just have to cook order by order which gives you nearly no flexibility.
2) Ordering takes to long. Just give me the damn order as a whole not piece by piece.
3) Rating takes to long. Rating your tacos really takes a lot time and you can't skip it or do something else at the time. This often causes overcooked meat.
4) The closing customers. They are just too picky. Most of the time my meat and building was perfect but they still weren't satisfied because of the wait.
Minor flaws:
a) Building is kinda slow. It's fine, but could be a bit faster.
b)Useless upgrades: the alarm clocks for the meat were kind of useless, because as soon as they rang the meat was burnt already.
c)The orders. Make the orders a bit bigger when they hang on the upper side of the screen and you could remove the placing of the orders on the right side of the screen.
