Nancy Chang on Pleasant St, best Chinese in town (no MSGs) and a nice atmosphere
Zipango sushi and steak - on Shrewsbury St - all around great food, service, drinks, atmosphere, valet parking
Piccolos - Shrewsbury St, expensive but very nice quality food and presentation
Zia's Grill - the best kept secret in Worcester - shrewsbury St next to Scano's bakery. only open for breakfast, lunch - go for Breakfast on Saturday or Sunday (before 1:00). They always have fresh watermelon and she makes things with really fresh ingredients. my favorite there is pancakes with white chocolate, peaches and strawberry or her breakfast quesadilla. wow
Sano Cafe at the Living Earth - not the most beautiful but wow, I always feel so good after eating their food - YUM, large selection of vegetarian, vegan and carnivorous (but free range) choices. good juices and desserts.
Corner Grill - on Pleasant St for upscale pizza. My favorite is Engine #9
I wasn't that impressed with the Union Station restaurant, although it is such a beautiful setting. I wish we had a tapas bar in town, a good burrito joint (although Tacos Mexicano Parilla in Green Island is pretty good and very authentic), and a cevicheria...
