The Via Lago Cafe—"The Beauty Spot of America"—was located at 837 Wilson Avenue. It featured "Uptown Chicago's Famous Illuminated Glass Dance Floor." The back of the card, which does not have a postmark, reads: "Good Food—Good Service. Refined Atmosphere for the Discriminating. Private Dining Room for Social Affairs and Private Parties. No Cover Charge at Any Time. Special Chicken and Steak Dinners served from 5 to 9 p.m., also a la carte. Dancing from 6:30 to Closing."
I think it's time for another jazz-era cocktail. This one is again from The Savoy Cocktail Book:
1 dash Angostura Bitters
1 dash Curacao
2/3 glass Brandy
Shake well and strain into cocktail glass. Frost edge of glass with castor sugar and fill with Champagne.
Of course, I don't have any Champagne chilling at the ready, so it will have to wait for another evening. (Also, I suggest you sugar the rim of your glass before pouring anything in—I typed in the directions as the book listed them.)
