It’s a brave new fast-casual-eatery world, with a high-end sandwich shop on every corner. But even in this crowded field, the Central Eastside Industrial District’s Stacked Sandwiches stands out: nailing the basics, upping the ante, and venturing, successfully, into the tricky world of salads and vegetarian sandwiches. The headliner is a reimagined French dip, that swaps out roast beef for heaps of pulled oxtail and uses the rich, rosemary-steeped braising liquid for dipping the crusty Pearl Bakery hoagie. Topped with havarti, onions, and cremini mushrooms, it tastes like a two-handed French onion soup of the gods.
