I'd driven past this place at least 100 times without ever entering based mostly on their outward appearance. It seems a tad run-down but that's probably due more to the fact that they've been a Bellingham institution for a number of years. The burgers are decent, better than Boomer's. The service was fast and friendly. And the prices are very reasonable.
All in all, if I were to suggest a quick, greasy place to get a bite to eat, Morrie's would be pretty high on my list.
