Stack'd does produce good food, but the rest of the experience is not so good.
The environment/decor confuses me because it's somewhere between bar environment where dirtiness/upkeep is somewhat expected and fancy env where I'd expect cleaner, better ambience.
The staff were not very attentive and when we walked in we sat a table that was just vacated. I'd expect the staff to see that the table still needed some cleaning/wiping but we had to ask for these things to be done. At least for that night, they didn't seem to check up on us enough to at least to see what else we needed.
Lastly, this one is an easy fix, but they don't seem to read the menu that customers fill out in full. If you order something on both sides, make sure you let them know you have something on the other side (eg appetizers are on one side of the sheet, while burgers and the main sandwich is on the front). They missed our order for onion rings.
