I purposely avoided Xoco in its early days, hoping for the crowds to die down a bit. The other day El Panzone and I showed up at 3:30, half past caldo time (soups are served only after 3pm). Not a single person in line so it was a breeze to order and get a table. We split a bowl of belly-vermicelli and a torta ahogada.

The caldo ($12) is nicely presented, garnished with fresh-as-can-be arugula and toasted sesame seeds. Submerged beneath the rich, chili-spiked broth are still-firm noodles and discs of zucchini. This soup didn't taste like it had been sitting around at all. The star of the bowl was the pork belly—tender slabs with a pleasant adiposity. A terrific bowl of soup that would be a perfect meal on a cold, blustery day.
I'll join in the praise for Xoco's torta ahogada ($9.50), a sandwich that's so often poorly executed in these parts. The whole grain bread may not be exactly traditional but the crusty loaf is probably closer in spirit to the birote of Guadalajara than the soft bolillos often used here.

The vertical presentation is unorthodox but it's thoughtful as well as visually arresting. Having only the sandwich ends submerged allows the eater to control the degree of salsa saturation as well as making this famously messy sandwich much easier to eat. The sandwich wasn't overflowing with carnitas but I thought it was tasty and balanced.
We ordered chocolate and churros which were brought out after our plates were cleared (service could not have been better for this type of restaurant).

I doubt I've averaged more than of cup of hot chocolate a year over the last decade but I have a feeling my consumption rate is about to increase. I think it's pretty much unanimous that Xoco's chocolate is superb. I much prefer the basic "Authentic" to the chili-spiked "Aztec" version (both $2.50). Churros (3 for $3) were fine but not something I can work up much enthusiasm for.
This was our first stop on a day-long gringo tour of Chicago Mexican food. After Xoco we stopped at Big Star to sample some tacos, beer and bourbon. This was followed by a brisk walk down Damen to Bar Deville for cocktails made by the ace bartenders from Cleveland's Velvet Tango Room. Sure enough the Tamale Guy stopped in with his usual excellent wares. Finally on the way to the Loop, we made a brief stop at La Pasadita for a carne asada nightcap. They were really in top form (no microwaved meat) that night. Purists might have a quibble here or there but I couldn't care less—that was one fine day of eating and drinking.
