Sometimes appraising coffee requires more than just evaluating what's in the cup. Cultivar's java may be attractive mostly because braised beef tacos are in reach, but it's more likely because they pour one hell of a cup of joe. The folks behind the dishwater share space with Good 2 Go Taco on Peavy Road, which offers fancy gringo versions of the tacos. The coffee is good enough to stand on its own merit. Roasted within days before brewing, they may be the freshest beans in all of Dallas. But throw in a flour tortilla stuffed with scrambled eggs, cheese and big wad of stringy beef for a compelling morning taco and you have a breakfast combo that will keep you fueled for days.
