Last night I had Falafels for dinner, it's a great way to eat healthy and keep your expenses down. My favorite way to make it at home is the Near East box mix, it's really easy and very affordable (I would recommend everything from Near East!).
If you fancy a night out I would recommend The Olive Tree, its easily my favorite restaurant in the city, and everything is pretty affordable. Not only is the food good but the atmosphere is one of the best! Along with chalkboard tables for the kids to draw on, they project Charlie Chaplin films! You can also go downstairs to the Comedy Cellar, where many of the great comedians have performed, such as Louie CK, Jerry Seinfeld and Steve Martin.
