We had rezzies for later in the day, but had a 90 minute dead zone we needed to fill immediately. We've been to Hop Atomica previously and absolutely loved everything, but we had no idea if they could be the answer to my poor planning 
We arrived at 12:30 and I walked in to let the front of house know we had no reservations but were hoping for at least a seat at the bar. The super-friendly staff offered us a spot on the patio and our day was saved! Their beer offerings are outstanding and even my 80 y.o. mom found a Sauvignon Blanc from NZ to make her smile. The absolute standout is the Pig & Fig pizza - truly perfect in its simplicity.
The only "warning" I will give is that regardless if you have a rez & dine inside, or happen upon the patio, you will order from a QR code. My mom was weirded out by it, but service was awesome and we did not necessarily feel the "loss" of a server interaction.
If they have not made your rotation yet, they are right in Germantown, behind the Germantown Lofts and across from Four Pegs on Goss. https://hopatomicalouisville.com/
