Via is one of my go-to places in Worcester for GF. Dinner can be a bit pricey, but lunch is really affordable and a good option.
They have a separate GF menu, so ask before your server sits you down if you remember. I've eaten here at least a dozen times and never had trouble. Servers seem to be knowledgeable and there are plenty of options to eat. You won't feel sad with your piece of grilled chicken and plain salad here. I always get the bolognese sauce, except on my birthday when I'll get the surf, turf and pasta, which is steak, lobster and bolognese, haha. You can tell the pasta is gf, but it is very good quality and frankly I like that, because I feel more confident that it is safe.
