The two main reason it is usually not good is 1. to small of a glass and 2. taste like cranberry juice! I do not like paying over 12.00 dollars for cranberry juice.
Come on! If you dare to charge me 10, 12, or 15 dollars for a Cosmo, please bartender put some vodka in it! There is nothing worse than paying such a high price for a drink and it taste like juice.
Well now I found the bartender and the place that makes it the best, and I wanted to make sure it wasn't a fluke so I have been back 3-5 times ordering them (such a tough job) and they have been consistently great! I was just back there last night and once again, the Cosmo is made to perfection. (Chilled glass, just the right mixtures of ingredients)
Hudson Yard Cafe - Bartender name - Barry!! Stop by and tell Barry that Deb sent you for the BEST COSMO in NYC and see if you agree with me.
