Apartment 138 is the drunk texter of restaurants: dependable, unfussy and ready for you even though it"s way past midnight. A sidewalk chalkboard announces fancier fare, but as the nondescript name of this rambunctious Smith Street destination makes clear, comfort food is the order of the day--or small hours of the dawn. It"s the kind of place where a basement game room beckons (pool, foosball, Ms. Pacman), as do a comfortable garden and a killer grilled-cheese panini with chorizo and peppers. Indulge its classier aspirations and you"ll enjoy serviceable pastas and salads. Better to dive into a juicy, well-cooked burger or a crisp, largely apportioned side of creamy mac and cheese.
