Looking at the menu and not knowing their *exact* ingredients, I’d say the Bespin Fizz, Cliff Dweller and the Outer Rim are the only 3 that would need to be made individually. Those, likely not by coincidence are also the 3 most expensive drinks (with the exception being the Yub Nub in a souvenir mug).
Everything else you could batch make without much discernible difference. Hand made would be preferred, as always, but I certainly wouldn’t have expected it in this location considering the fact they’ll be slammed always. And considering it’s like only for 4-5 hours per batch (or way less), that should be adequate.
Also, note that no brands are mentioned; and that will have a much larger impact on the quality of the drink vs batch/handmade. As a liquor snob, that’s where my concern would be
