I adore Silly's for so many reasons. As a person with a family who cannot bear the thought of eating vegan/vegetarian, this is a place that we can all agree to go to when they visit. There are many wonderful vegan options here (fantastic falafel, great fried pickles with a vegan sauce, awesome veggie burgers, desserts and more) along with many meat dishes to choose from. This is a great place to go if you're having a craving for food that might not be very good for you, though. They certainly serve greasy bar-style food but it is quite tasty!
The atmosphere is also veeeery cool; the decorations make the restaurant look like one big party. The waiters and waitresses (there are certainly more of the latter) are usually very nice. I've only had one encounter with a waitress being very unfriendly.
Cons: Not healthy, but that's okay sometimes!
