Tried for the first time and did not enjoy the wings at Bistro (or the fries for that matter). The herby-ranch sauce came in some St. Louis branded plastic dipping sauce containers... not that pubs have chefs who slave hours over home-made dipping sauces, or that it really even matters much... but I found the sauce quite unpallatable. The wings were way too dry and not even remotely spicy (I ordered hot).
PLEASE NOTE... It seems I am in the minority on this one, many chowhounders swear by Bistro and St. Louis! I much prefer real buffalo-style wings, though many people have left comments that places like Duffs are too "vinegary" -- the simple fact is that wing sauce is generally hot sauce and butter, and hot sauce has vinegar as a main component..
