I went to Spoon House three times this past semester, and the thing that brings me back every time is their Korean tacos. I had Korean tacos for the first time a year ago, in LA, the home of Korean-Mexican fusion. Despite being two thousand miles away, Spoon House's tacos are definitely good enough to compete with those on the west coast. To know my knowledge, they're the only restaurant in town that serves such a dish; they're both delicious and reasonably-priced, which adds to their good reputation.
Go for the beef bulgogi taco and the spicy chicken taco, those are the two best. Personally, I feel that they are too heavy to be eaten exclusively as a meal, so you're best off ordering a small rice or noodle dish with several tacos on the side, so it's easier on the stomach. I would avoid the quesadillas, the saltiness overwhelmed the taste of the meat.
I can't really speak for the rest of the menu, but those tacos are quite a gem.
