Medio

Although this area is not lacking in options for a quick snack, Medio is one of the few to offer a small seated area to enjoy your lunch in.
The menu is not groundbreaking, but it is extraordinarily cheap. For instance, you will rarely have to pay over 3.50 for anything, while its own range of subs will set you back half the price of what you would expect to pay in most other places.
I can recommend the baked potatoes. It’s hard to get them wrong, admittedly, although it is staggering the amount of places that do. Medio doesn’t. And it charges 2.50 for them. Fine by me.
