Indoor playgrounds for crawlers

Hi all,
I have a couple of 14 month olds, walking with the aid of nearby furniture, and I'd like to take them somewhere tomorrow for a change-of-pace. I was told about a play area in the Deutsche Museum, but it seems the kids need to be 3 years old for that. Is there anything else like this? It is "spur of the moment" so I can't make use of appointments/memberships/registrations.
thx!

There's supposedly an area for under 3s at CocoLoco. Comments and some other suggestions Toddlers & rainy days. Good luck

Thanks jml. I actually went to Sticky Fingers and it was a good time. Thanks again,

On another occasion you might try Hofbraukeller (Innere Wiener Straße 19) as they have a play room for kids. Can be quite crowded on weekends however.
