Chain restaurants are creatures of convenience: They're the places where you eat when you don't want to think about where you want to eat. The best of them insinuate themselves seamlessly into your world and your lifestyle -- and Tokyo Joe's is definitely one of the best, not just for Denver, but for the fast-food world at large. The Japanese noodle-house concept is both the perfect extension of the modern American fast-casual business model and a working fit for Colorado, with its long history of Japanese immigration. Beyond that, Tokyo Joe's is just good --with a DIY menu long enough to remain interesting over many repeat visits and a staff absolutely committed to making sure that everyone gets exactly what they want and need.
