"Ooba Tooba" is an alternate spelling of Uba Tuba, which is a beach in Brazil.
Ooba Tooba's been on the Eastside for more than a decade—it's a local/family-owned mini-chain, and its fifth outlet is grand-opening at 209 Broadway near John (where 17 different Thai restaurants have been) today. While it's a "Mexican Grill" and makes five fresh salsas daily, it's also a little all over the place (or as they say, "eclectic")—from the "all American burrito" of just meat and potatoes, to the vegetarian Bollywood burrito with "grilled green beans and a sweet ancho crema." It sounds weird and possibly good, and if you're going to try it, today's the day—all day long, from now until 6 p.m., they're donating 50 percent (FIFTY PERCENT!) of sales to Lifelong AIDS Alliance. Which is very cool.
