my groupon was one day before expiration, and the staff/owner of Mahtay were very polite and helpful. Really great place with an awesome unique atmosphere. nice to have something in St. Catharines like that to go to! ps they also have a liquor licence now, and feature a funky menu. as well, they have interesting entertainment and charity nights (jazz thursdays, YWCA fundraiser - women in song +art, etc)
