I just ate Zen for the second time and they just keep it consistent. The food is very good, very fresh and comes very fast. And excellent lunch choice for the downtown crowd Monday thru Friday. And the prices are very good. You can lunch for under $5 if you just get a water.
The service at the counter is very good, very polite and friendly.
I would recommend Zen for anyone looking for a real good lunch in the downtown area. They are in the Arcade almost under the stairs.
Be prepared, it is cafeteria style seating shared with other resturants so don't expect linen tables cloth.
As was stated in other review CASH ONLY!
