I did a search for vegan food on Yelp and the Mac Shack came up. Last weekend I went to eat there and asked the cashier if there were vegan items on the menu. The cashier did not seem to know what vegan means, so she asked the girl working next to her. The second girl said they do not serve any vegan items. The way the second girl replied to her co-worker left me wondering if there really were not any vegan items on the menu, or if she just did not want to be bothered telling me what items were vegan. The place wasn't very busy when I was there, so it wasn't like she couldn't find the time. Although a few menu items looked as if they could be vegan, rather than trying to ask, we just left.
It looks like a nice place, but for us, the customer service was lacking. If there are vegan items on the menu, I hope someone will point them out. There are no designations, as far as I could see, on the website menu.
