Brightest lights from my last visit (no disrespect to all the usual recs, either):
For coffee, Holy Spirit Espresso (best espresso I found in town, but the owner is retiring 1 October, so hurry), Iconik Roasters, or Capitol Coffee.
For breakfast, Cafe Mamou, Clafoutis, or Tune Up Cafe (Harry's Roadhouse is great, but get there early).
Lunch: Midtown Bistro, Los Potrillos (birria on weekends), The Beestro for carry out sandwiches, or food trucks, either El Sabor Tapas, Bang Bite, or La Loncherita Salvadoreña.
Dinner: Joseph's Culinary Pub, 315 Restaurant and Wine Bar (Santa Fe cassoulet is good, believe it or not), Radish and Rye, Paper Dosa.
Beer and misc: Fire and Hops, Loyal Hound (good fish sandwich), Rowley Farmhouse Ales.
Worth Repeating: Jambo Cafe (Caribbean Goat Stew is terrific), La Cocina de Doña Clara, El Parasol, Raaga.

This is great - thanks! Lots of places I haven't heard about from the usual sources.

Was considering a trip to Santa Fe and doing some digging when I learned that Sante Fe Bite (formerly Bobcat Bite) is closing in October. From the website:

Open Until October 26, 2018 - and then we're gone...

We’d like to thank the community for their loyalty and support over the years...We are leaving for a number of reasons, some personal, some logistical, our lease has ended but basically am not able to do this kind of work anymore...
Our last day will be October 26th. At this point we have no plans to relocate elsewhere.

One big strike against my potential travel plans.
