Waltham is home to many international restaurants and grocery stores. Many people travel to Waltham from Boston just to have dinner on Moody Street! Hopefully you can find some familiar foods from home or at least the ingredients to cook a meal for yourself. One word of warning about the restaurants, though: most of them are Americanized. You could teach us a thing or two! For more information about Waltham restaurants try here.
You can also order from a number of restaurants and have the food delivered to your room via a service known as Take-Out Taxi. Call them at 781 891 3663.
