Wallflower LuehmannJune 11, 2013So worth the trip! We were foiled the first time by a private party, but were rewarded the second time with a fabulous meal and fun, interesting drinks.
Krista COctober 11, 2015Off the main drag, awesome cocktails and great service. Reminds me of one of my favorite places from my college town. Get the Looking Glass.
My favorite drink is their Blue Velvet - 42Below vodka, fresh lemon, orgeat, creme de violette and fresh lavender. If its not on menu, order it, they can make it for you. Boulder's best cocktail bar.
Cobey FlynnJanuary 11, 2015Good cocktails, nice bartenders, yummy balls! Get a sample of the bronuts donuts: Chocolate Salty Balls and S'more Balls were our crew's favorite.- Bill FlinchbaughSeptember 17, 2022Cocktails, whiskey flights, Happy Hour, atmosphere. Beer selection could use some work. Draught faucets are for cocktails.
CraigMarch 28, 2013Very knowledgeable wait staff. Ask them to help with your drink selection. I ended up with 2 drinks off of the menu that were outstanding!
Mike GrossMarch 13, 2013nice absinthe selection & ridiculously knowledgable staff. Boulder's best bar for sophisticated imbibing without gettin' gussied-up.
TaylorFebruary 8, 2012Sazerac. A cocktail that so few places outside of New Orleans do well. Bitter Bar does it well. Recommended.
shelley pierceMay 5, 2015even better cocktails now that they ditched the restaurant and went full bar mode
- Tundra Restaurant SupplyJuly 22, 2013Tell the mixologists what flavors you like and they'll fix you up something tasty!
The best Moscow mule. They'll hold your ID though so you don't steal the fancy cup
D.j. RicardAugust 25, 2011Green Devil is a great cocktail...Absinthe, Patron, Lemonchello, Cucumber, and Thai Basil! Rockin!
Tom FeldhusenJune 15, 2011It's no longer on the drink menu but ask for a "kiss the sky" it is one of the best gin cocktails ever.
The beer and a shot of whiskey is a great deal and delicious!
Angel's Envy with a big ice cube and those amazing cherries.
amazing cocktails. have one of their bartenders make you something. it'll take a little while, but it will be totally worth it.
Boulder BarsOctober 5, 2010Order a 'Just Dan' from the black book. It's a martini with pomegranate and muddled blackberries. Awesome!
skip the food, go for the cocktails. ask mark or matt to introduce you to their masterpieces: vieux carre, manhattan, bijou no. 2...
