I find drinks that are traditionally served in stemmed glasses are difficult to carry (I'm a wheelchair user). What terminology would I use if I wanted to order a drink like a martini or Manhattan served in a rocks glass (but without the ice)?
I believe the type of glass you are looking for is called an "Old Fashioned glass" named for the cocktail typically served in it. Depending on the size of the drink you may possibly want request your drink in a "Double Old Fashioned glass". I would hope that simply requesting your martini be served in an Old Fashioned glass would suffice.
