Pros: go there for the corned beef on rye with a side of your choice. That's my usual order for about a decade plus I've gone there. Nothing else is needed.
It's a small place, always packed. Which is a good thing, shows it does well. Service is good. It's a deli, doesn't pretend as it was mentioned earlier. Portions are a decent size. Tons of flavour.
Cons: slightly on the more expensive side, worth it but still. Can get really packed, where finding a seat is difficult at times. Other than that, it's a def must to check out when in this area.
