Michael Schlow tells Grub Street via a rep that he will replace Kenmore Square's Happy's with an as-yet-unnamed Mexican restaurant, which will open in early February. Says Schlow: "Call it Murphy's Law, but on the eve of closing Happy's this Saturday, we had one of our busiest weekends since opening last year. If nothing else, this solidifies our belief in the neighborhood and commitment to our customers. We're excited to introduce a new Mexican restaurant to the Fenway area in early February. Look for a margarita menu, lots of different quesadillas, awesome tacos, 70 different tequilas, and of course, a new signature burger...this one with avocado, bacon, and chipotle. Just in time for the Red Sox season, the new restaurant will offer Boston fans a fun spot to grab a couple beers, a quesadilla, and some tacos on the way to the game."
