what about this one ?
+++ New tavern upgrade : right now, we have the table, the tray, the tablecloth, and the floor that we can upgrade from the right side tabs in the tavern room. We could have a fifth tab for cups upgrade with a cooldown bonus on the Aid + VisitTavern :
-2 minuts -horn shot : cost 1000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 2mns
-4 minuts -wooden goblet : cost 2000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 4mns
-6 minuts -clay cup : cost 4000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 6mns
-8 minuts -porcelain mug : cost 8000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 8mns
-10minuts -ceramic bowl : cost 16000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 10mns
-12minuts -glass tankard : cost 32000 silver to upgrade and reduce the cooldown on Aid + VisitTavern by 12mns
at max level (glass tankard upgrade), the glass tankard would allow you to aid/visit tavern every 23h48 minuts (important for your playerbase with a routine)
*** New Great Building : Architect Lounge 3 x 3 footprint (No age) using the -Louvre Museum Pyramid- model (maybe)
requires The Future Era goods to build (350ish of each?)
Bonus would be -City management : allows the production of boosts/kits every 7days, every level unlocks new boost/kit
-lvl 1 City management allows production of "Motivation kits"
-lvl 2 City management allows production of "100 tavern silver"
-lvl 3 City management allows production of "10% Coin Boost"
-lvl 4 City management allows production of "10% Supply boost"
-lvl 5 City management allows production of "Mass Motivation kits"
-lvl 6 City management allows production of "10% defender boost"
-lvl 7 City management allows production of "5% attacker boost"
-lvl 8 City management allows production of "boost crate"
-lvl 9 City management allows production of "Store building"
-lvl 10 City management allows production of "One up kit"

*at higher lvls you would get higher chances to get better boosts (without breaking the game balance, of course)
these are only suggestion % and the tooltip does not need to indicate all this, just "ABC lvl unlocks a chance to get XYZ boost/kit" would suffice, I guess...
