It was awesome, not dreadful! It was as late 80s/early 90s as you can get; like my childhood wrapped up into a dining space. Solely for nostalgia reasons, though -- it was obviously time for an update. Having the upstairs was nice, though, and it seems like they removed that for Connections. I think that's a mistake.
I'm not sure you're right about it holding up better. Design trends always change. While the current trend is pretty bland which seems like it would hold up better, it probably won't. In 15-20 years things will have shifted into another direction and this space will likely look as outdated as Electric Umbrella does now. It's the reason even chain restaurants typically do major design overhauls every couple of decades.
Also, I really like the new murals.
