Bistro is going to have French waiters with accents. Your napkins will be folded into the shape of little tuxedos. The wine list will be expensive. Personally, this is probably my favorite WDW restuarant but I would consider it upscale. Citricos is not as "fancy". I do not think the food is as good as Bistro. The first time to Citricos, we really enjoyed it. However, 2 subsequent return trips were more disappointing. Bistro has been excellent each time (it's always our last dinner of the trip). But I wouldn't call it a meat and potatoes kind of place. Neither is Citricos for that matter but it is a little more casual.
