Time Out says
At Bar Alexandra—the hip younger sister of Bar Alexander in the Altstadt—you might have to wait a while for a table, but once you’re seated you’ll understand why. A sleek, modern, decadent interior featuring red walls, leather furnishings and dark accents complements the selection of premium spirits mixed in unexpected ways. The bar has scored awards for its barrel-aged cocktails—concoctions that are mixed and aged in a small barrel behind the bar, like Negronis and Old Fashioneds. If you’re not looking for anything fancy, it’s a lively place with great music and a fun atmosphere, especially on Wednesdays: to get over the mid-week slump, Bar Alexandra offers student days, with cocktail deals running for only five euros each for students.
