What can I say about Grand Marier, Texon Silver Tequila in Juanita Greenberg's top shelf Grandma's Texon 'Rita? It's tangy and tasty and everything that perfect margarita should be. And large. Large is good. Juanita Greenberg's is located at 339 King Street in the Upper King Design District. Everything is made fresh on the spot. Next time dinner. Will report back.
