The majority of my beers on tap are Euro-Lagers, so the temp is kept at 36-38 degrees. Yes, that is a bit cool, but like others have stated you can allow the beer to warm a bit in the glass.
I like Porters around 40 degrees.
When in a bar or restaurant (very rare these days), a room temperature glass is always requested. Can't tell you how many times my beer was served as a slush. And I don’t like to chew my beer.
