Walked in late lunch time with a small coffee and was stopped dead in the foyer with "I'm sorry you can't bring that in here". No "welcome", "hello", or any other reasonable greeting. I asked if I could step in to the establishment and finish my coffee just inside and was denied. Don't feed me the BS line about the city says this or that, I've walked in to countless restaurants with coffee in the past 15 years in Madison and never had that happen.
This was the rudest welcome I've ever had at a restaurant here.
I had my son with me so to not disappoint him we played games for a bit but went elsewhere for lunch. Didn't feel welcome here at all and we won't be back. Good luck being jerks to your customers D&Bs.
