I've never had anything but great experiences at Zen Zero. The Singapore Noodles is my favorite dish. Prices are so reasonable and the service is always great. It can get a little noisy with the open kitchen but the atmosphere is wonderful.
This place is hot spit! I enjoy a number of things from their menu but I like the #33 Nepalese chicken curry the best. True, if you hit it at a super busy time the quality could suffer a bit (rice has been over cooked once or twice or a lesser amount of meat in the dish) but still a great meal for the price. Many times I have ordered and had my food brought out to me in under 4 minutes (and it was made perfectly)
