Chive and Thyme Café in Flemington has become our go to place for an excellent lunch at a very reasonable price. It's in the building where the Blue Fish Grill used to be and has limited hours (10-4 as I recall) because it's primarily a catering operation.
It's run by two women who used to work at the original Baker's Treat. One was the executive chef and she has a knack for serving up delicious food very quickly. The only dish that disappointed was macaroni and cheese that had clearly been reheated (too much) in a microwave. Everything else has been freshly made and the sides, which are included with most dishes, are excellent. I nearly always choose the sweet potato fries.
This place is very casual. You order and pay as soon as you go in and the food is brought to your table. If that's not to your liking, don't go, but you'll miss out on some really good lunches!
