bistro (n.) Look up bistro at
1906, from French bistro (1884), originally Parisian slang for "little wineshop or restaurant," which is of unknown origin. Commonly said to be from Russian bee-stra "quickly," picked up during the Allied occupation of Paris in 1815 after the defeat of Napoleon; but this, however quaint, is unlikely. Another guess is that it is from bistraud "a little shepherd," a word of the Poitou dialect, from biste "goat."
