Stack'd is great if your expectations are set to the right level. This is not fine dinning, of course, but it was great for a very casual dinner when a good burger is the goal.
Everyone in my party had a burger, one from the menu and two "build your own". No one was oooohing and aaahing over their food, but everyone was was perfectly happy with what they got (and the glutten-free bun choice was appreciated). The side salads were fine, nothing spectacular but perfectly adequate. A nice selection (30ish?) of beers were available on tap.
The service was good - friendly and reasonably prompt - and it was not too loud even though we were there on a fairly busy Friday evening. Having signed in on NoWait ahead of time, we were seated immediately upon arrival.
I would certainly go again when it is what the occasion calls for.
