I really really like Triple 7! Conveniently located within walking distance of my apartment, it is my favorite choice for late night beer and snacks. They have a great deal at happy hour and after midnight on weekdays when beers are only $2 (and their house-brewed beer is totally delicious). I keep going back for the Black Mud (brewed with coffee beans; I have yet to try dessert here, but I think this would pair fantastically with a brownie or cake something) and Winter Blues (delicious, delicious blueberry beer).
We have always had attentive service (on our last trip, our waitress was wiling to circumvent the late night menu and get us the mozzarella sticks my husband suddenly desired, which was super nice of her) and a good time for not too much money. Plus they are only closed between 7am and 11am, and I am never up at those hours, so they are effectively open 24/7. HOORAY!
