I really like Fishbones in Chelmsford. Consistently good food, nice atmosphere with an outdoor patio and lively bar. Wonderful fresh seafood. The special they feature each night are always worth trying. They have everything from raw bar, fried seafood, great pasta dishes with seafood, and traditional favorites.
I would hit Sakura on Summer street for sushi before I went to Feng Shui. Feng Shui is more of a one stop shopping for Asian food kind of place. I guess if you have some in your party that want Chinese and some that want sushi, it may work.
Being in North Chelmsford, you are also only miles away from downtown Nashua with many options, just do a search on Nashua.
The city of Lowell is very nearby. Check out the posts on a Cambodian food crawl done in Lowell as well as other Lowell posts. Off Drum Hill Rotary and Rt.3, is a very good Pho restaurant. It's past the Walmart, on the right side. Sorry but I can't remember the name.
re: three of us
The sushi place in Chelmsford is Feng Shui. I haven't been there yet but I've heard very good things about it.
Amici Trattoria is a very good, hole in the wall, italian restaurant. Nothing fancy just real good pasta. You'll find it in the little marketplace across the street from Marshalls.
Thai Jasmine is a great restaurant on 110 close to the border of Chelmsford and Westford. Their Pad Thai, curries, and chicken wings are a must order everytime I go.
For breakfast I'd check out some of the diners in Lowell. Owl Diner is one of the more famous ones, and easy to get too from Chelmsford. (Just straight down Chelmsford St. to Lowell past the rotary).
