Awhile ago a Chowhound asked for good restaurants in Guelph. One of our family lives there, and is a member of several local musical groups. She introduced us to Diana Downtown, an Indian restaurant that also serves a regular menu, when musicians and ourselves gathered there after a concert last year. Last week we revisited Diana Downtown at 141 Wyndham St. North before another concert. One of our party, the timpanist, had to get away quickly to set up his instruments and asked for quick service. He had his meal in 10 minutes. I ordered buttered chicken - delicious. It was lunch so I took half of it home. I'd recommend Diana downtown for its cuisine, its central location, the decor and the friendly wait staff. I plan to return there.
