I really enjoy the core of Vienna. Beautiful architecture and public realm, and more well treed than many older European cities.
The women also find blonde hair quite exotic.. LOL

For all of that..........the culinary scene is very meat and potatoes. German-influenced......what's a vegetable.........I get the appeal to you in that way..... LOL, but there's very little in the way of foods of thew world.
Don't expect to state your craving for Jamaican Patties, Roti, Tacos, Pad Thai, or Pork Vindaloo while in Vienna.....
Vienna also closes early...............for a man such as yourself for whom the witching hour is just the mid-point of your day.........Vienna is 1/2 asleep by 9pm.........and dead to the world by midnight. (subway closes at midnight Sunday to Thursday; though it is open 24/7 on the weekend)
A further reminder, not all of Vienna is the old centre, this too is Vienna:

This is more likely in your budget than the City centre.
Just a reminder to keep grass-is-greener syndrome in check.
