Essentially, not very much. A bistro is a type of restaurant and is just further defined as smaller and more casual than a fine dining establishment. Often, a bistro is described as more of a neighborhood restaurant with community ties, and a warm, cozy, inviting atmosphere.

A bistro is most commonly associated with upscale, often french cuisine, and this is fitting due to the fact that the word bistro most likely originated in France. Etymologists identify the first uses of the term bistro in France in the early 19th Century.

Bistros are known for their intimate and relaxed dining environment, offering a cozy setting for customers to enjoy their meals. Unlike traditional restaurants, bistros often feature a smaller, curated menu, typically focusing on locally inspired or classic French-inspired dishes.

Bistro vs bar Both bistros and bars serve alcoholic beverages. However, unlike bistros that serve full meals, bars either do not serve food or have a very limited menu of snacks and finger foods.
