News for the Traveler

A small guide called ''The Interstate Gourmet'', written by Neal Weiner and David Schwartz, can make your trip from New Haven, Connecticut to Burlington, Vermont, or any shorter distance in between much more of an adventure. The book is a collection of little restaruants that are close to the interstate and offer good, inexpensive food in an attractive setting.

About 100 yards from a Connecticut exit on I-91 is a little Polish place with wonderful food and irrepressible charm. There's a Greek restaurant with dancing just three blocks from the road in New Haven. In Hartford, you're almost in Little Italy, and Brattleboro, Vermont has one of the nation's first natural food restaurants. At all of these places the food is better and frequently cheaper than at the franchise establishments. And the atmosphere is always more interesting.

The route covers most of Interstate 91 and the Vermont portion of I-89 -- frequently traveled by country people heading for the cities, and city people seeking rural peace. Most of the restaurants are within two minutes of an exit.

To order the ''Interstate Gourmet'' write to Oak Cottage Press, 2 Forest Street, Brattleboro, Vermont 05301. Enclose $3.95, Vermont residents please add 3% sales tax.
