Taprooms vs Bars

One of the biggest suppliers of beer to local type bars, Molson-Coors, is complaining that local microbreweries with taprooms are cutting into their business in a noticeable way.

Bummer dudes. First let's see what exactly is being compared.
Beer:
N.B. = Coors, Miller, Bud. Options = regular or light.
T.R. = The house brews. 6-12 variants ranging from light to black. May include fruit or other flavorings. YMMV but you knew that in advance.
Food:
Neighborhood bar = grill in back producing burgers and fries. Probably better than fast food but not greatly.
Taproom: These places seldom have a food production facility, but they cover the legal requirement to supply eats by contracting to a food truck to park outside. The truck is sometimes as much of the attraction as the beer inside and every one is unique, some much better than others.
Ambience:
N.B. = Loud background music, usually R&R, and wall-to-wall TV's tuned to various sports channels. Noise level demands yelling to make yourself heard across the table.
TR = Softer background music and probably only one TV, frequently tuned to a news channel. Fox if you're lucky, CNN if you're not. If you're really lucky, there won't be a TV. Conversation is easily possible.

So why did you go to whichever place you went to in the first place? My idea of a drinking establishment is a dimly lit place with many small (2-4 seats) tables with classical music playing softly in the background and a couple of larger tables in the back room for party groups. Craft beers and single malt whisky. Food = appetizers.
