I have been to the Livermore twice now, once on a Thursday towards the evening when it opened, and now again on a Saturday night.
I was there with a girlfriend of mine after just having dined at Casa Rasta next door.
It's a neat space and owned by the Bar Marco crew, so they have extended the model of craft mixology with premium ingredients.
It was crowded but not brimmed, [it was 10:30pm so this may change throughout the remainder of a Saturday. I ordered a whiskey sour with the added non-required egg white ingredient. The mixologist was good enough to ask which version I preferred.
Now to outline the common criticism of the bar: It's too popular!
Each of our drinks took 20 minutes to get to us and another 15 minutes to get the attention for the final bill. Usually, this is a death-sentence for a popular bar however the Livermore will get a pass.
As the model serves craft drinks only [no soft drink products in the vicinity] a drink will take a minimum of 3 minutes to make from start to finish + ordering time + adding the drink to queue [cash register] + delivery. this averages to at least 5 minutes a drink per customer.
At a rate of 15-20 intended orders over a span of 30 minutes will make it impossible for this bar to deliver a premium drink in a "manageable" popular bar delivery time of 10 minutes or less [can you tell I am writing this review during MBA Operations class??]
However! This system is perfectly acceptable when you are visiting the Livermore during an off-peak time. The atmosphere is lovely and the decor is appropriate and the bar tenders have seemingly lost their Bar Marco snob attitude in their commute from the Strip District.
Conclusion: Go to this bar for delicious drinks either to start off the night on Fridays and Saturdays or during the weekdays. - Will be returning there myself during that timeframe.
