Origin Thai recently opened a third location on Mount Airy Road in Basking Ridge, in a new strip mall just off Route 78. I've always been partial to Origin in Somerville, so I was inclined to like this place anyway. It's a beautiful room and it was positively jumping when I was there. We had a couple of appetizers, the green chicken curry, pad thai and a dish of jumbo shrimp with chopped scallops. The jumbo shrimp were OK but not that exciting. Everything else was thoroughly enjoyable. The service was friendly and attentive. I had some concerns about Origin's ability to sustain a third location -- or fourth, if you count Bank 34 -- but they seem to be pretty good at juggling all these restaurants. It's a great addition to the area and, between the great food and good value, should give Ciao and 3West a run for their (expense account) money.
