For the uninitiated, T&T is basically what happens when you combine the selection of a massive Asian supermarket with the polish of a Whole Foods — minus the $9 asparagus water energy. Think fresh-baked pineapple buns, a hot food bar that puts Safeway's sad rotisserie chicken to shame, and produce aisles stocked with the kind of specialty items that Bay Area home cooks have been driving across three counties to find.

Speaking of which: the mango situation around here deserves a word. If you've ever wondered why the mango topping on your boba or shaved ice tastes impossibly sweet, but every mango you grab at a chain grocery store tastes like it was picked during the Eisenhower administration, you're not alone. The secret? Skip the Safeways and Targets. Hit up your local Asian supermarkets — Lion Market, H Mart, 99 Ranch, or the small produce stands in the Richmond and Sunset districts. Seasonal Alphonso and Ataulfo mangoes are the real deal, and they tend to show up at these spots weeks before any major chain bothers to stock them.

The free market works beautifully here. Demand from knowledgeable consumers drives these independent and specialty grocers to source better product, and competition keeps prices honest. No government mango task force required.

T&T's arrival is a win for consumer choice and a reminder that when you let businesses compete for customers instead of erecting regulatory barriers to entry, everybody eats well — literally. Welcome to the Bay, T&T. We've been waiting.
