I've been to both the original Owl Bar (not cafe), and the Eubank spawn, and I must say: the original has an exceptional green chile burger, and the Albuquerque one has truly baffling milkshakes. The burger in San Anton is small, true, but it is so messy, so delicious, so heart-meltingly full of NM green-chile goodness that one hardly notices; it's the very paradigm of what a NM green chile burger should be. The shakes at the Eubank one defy reason, the peanut butter one alone so heart-rendingly succulent as to totally obliterate the memory of any other milkshake one has ever had-anywhere. Both these places have unbeatable atmosphere: the original, dark faux-dive, the progeny cheerful 50s nostalgia.
Pros: great green chile, atmosphere, milkshakes
Cons: crowded (Eubank), limited breakfast
