Love me some Tin Tin. Best time to go is around 11A or after 2P after that is a line out the door but even so it moves pretty quick. However they are open on Saturdays and there is never a line. There is seating above with a tv (yay!) or you can sit in the Ivy or take a chance and go outside and get some *ahem* interesting people watching sights in.
Nice, enthusiastic cashier, good prices, fast service and large portions-you can't beat it.
