Mexican Coke at Dorado Tacos & Cemitas

We visited Dorado Tacos & Cemitas in Brookline earlier this year, and enjoyed the experience. Now a little email tells us the restaurant has "Mexican Coke" on offer: a nice addition for those who freak out over the uniquely flavored drink (the drink is typically sweetened with sugar, as opposed to high fructose corn syrup, in Mexico). Tacos Lupita in Somerville is the only other restaurant near Boston we've heard of consistently offering the beverage.
