Pros:
1. Staff are friendly.
2. It's 24/7.
3. Very nice selection for a convenience store. I like the brands they choose to stock. They also have a nice selection of middle eastern products.
Cons:
1. A bit expensive sometimes.
2. It's not an aesthetically pleasing place.
3. The tap (aka "paypass") credit card feature is broken, and rather than fix the problem they've just let linger for years (I see another Yelper has complained about this exact same issue.) I would prefer to pay with tap -- particularly at what is essentially a convenience store.
