All Days and Onions closed in June. Isabella's is good but don't try to get a grilled cheese, if you are an adult. that really annoyed my 44 year old daughter! Your Belly's Deli is a great sandwish, soup place, Less than a 1/2 block north of the intersection of US& and VT9,(known as the 4 corners) Behind the Clip Shop(North St) on Pleasant Street. A Short walk from Main Street parking.
Madison's on Main St feature gluten-free items.For old fashioned diner type food go to Full Bellies(open til 2pm) on Main, one block west of the 4 corners. Peppermills a few blocks west on Main is open for lunch Sat and Sundays.
The Bean and Leaf is pretty good. It has the usual coffee fare, plus a decent selection of lunch items. It's located behind the Paradise Motel, which is on Rt. 9 westbound, across from the Hemmings Sunoco station.
And Lil Britain has great fish 'n chips and they are open for lunch (and dinner), Tuesday through Saturday. http://www.lilbritain.com/index.htm
Izabella's is good. I find it a bit on the pricey side. Blue Benn is always a favorite, albeit completely different from Izabella's. Be warned: Blue Benn is cash only.
I agree with Izabella's, it's a nice small cafe with good food. The Blue Benn Diner is also a great place for lunch, as is Your Belly's Deli if you are looking for a good sandwich. I haven't been to Alldays for lunch in a number of years so can't comment. As far as coffee shops go, South Street Cafe is the best place, hands down. It is around the corner from Izabella's just south of the Four Corners.
