I've been a fan of Curry Zen since they've opened.
Food: A fine example of how keeping things simple and focusing on a specialty delivers a reliable, quality experience. I think they've recently expanded their menu a bit but I have always been thoroughly impressed with their Japanese curry. The curry itself is standard for their dishes. You pick your meat or veggie option, pick your level of spice and they add rice and voila...you have an awesome dish. They also have a list of add-ons that you would typical see at other places like ramen spots.
Facilities: They've recently expanded (that's a good sign). And now they're double the size that they were when they opened. There might be a wait....but given how fast they get their food ready...wait times shouldn't be a problem. but as a guest, please keep to the same manners as you would with Monta next door...don't hand around...get in...eat your food...and dip.
Staff: This is more of a food-service spot so, by design, the staff won't chat it up too much. But they are friendly, quick with service and check back frequently.
Now I am getting hungry.
