Not bad but a lot of task coul be automatized, for exemple, building a table, when you have all the prereq, shoul be buidable in one click once you already build one at least (see Craft The World for example, once you build a receipe you can build it in one click because it can contain 9 prereq...).
An other bug : restaurant lvl 800 at upgrade 6 give less than cafe 900 at upgrade 5. So 100 level of an inferior is better then an upgrade of something better ??? And the price of 100 level is the same for the 2...
If you allow me : you should try to use decimal separator and thousand separator in a better way... same for some units in the research lab. 100.000 thousands, WTF ? So it's 100 millions ??? Why put 100.000k instead ? And big bug, if the hotel is 100 000 thousands, why the previous one is 550 000 millions ??? it's 550 000 times more !!! o_O
