Everybody loves Tat’s. Or at least, every guy loves Tat’s. The scruffy little sandwich place on a scruffy stretch of Occidental is always attended by a long line of guys. With its Reubens and Cheese-Steaks, it’s like a slice of the East Coast in Pioneer Square–but really, not like those ersatz “Jewish” delis that spring up as a vanity project in Seattle every few years. And one of the things I find most oddly eccentric about it is the pricing. Everyone knows that in order to up-sell, you make the bigger item seem like a relative bargain. The tall coffee at Starbucks is about twice the size of the short, but only costs 30 cents more (or thereabouts). You can get a giant movie theater popcorn for just a fraction more than what the smaller bucket costs. Etc. Standard food industry practice.But Tat’s turns that on its head. There, an 8-inch Italian sub costs $7.50. But if you want a 12-inch–that is, a sub that’s 50% bigger–you have to pay 12 bucks, or 60% more. In other words, they downsell you. Call it Tatonomics. I don’t understand it. (Maybe you do?) But apparently it works for them.
