I ordered ahead through the app, and said I would pay with cash when I picked it up. When I got there my food was ready to go but I still had to wait on my milkshake, which I appreciated because who wants a melted milkshake? It wasn't really a wait though, because it took less than a minute for him to make it. I showed them my Groupon, paid the remaining amount plus tip, received my food, which was hot & delicious, and waited for my milkshake, but was still in and out in less than 4 minutes. This is why I will always come back. Well, that and my calzone addiction I suppose.
5 stars, 10/10, 100% do recommend.
