We had a small group of friends who went there after getting donuts across the street at Peace, Love, and Little Donuts (highly recommend!). We bought delicious drinks to go with our donuts. THEN we were told we couldn't eat our donuts there! I was devastated and wanted to return my drink - which is apparently not allowed at coffee shops.
I would NOT recommend Tree City due to their silly and poor customer service. We will not be returning and will instead boycott from across the street while eating delicious mini-donuts.
