I don't think you're supposed to mix champagne and beer in one night unless you're prepared to suffer the consequences the next morning, but tell that to Karim Rashid. His Happy People reversible glasses are all dual-bowled so you can have a cognac, bottoms up, and move to tequila. Every glass is made of mouth-blown crystal and has a name. Ming Yiu is the most sophisticated, I think, half martini and half sake.
The glasses start at $85, and go up to $150 for fancy Naomi.
